Determine the installation site

1698_datchik_dvizheniyaThe correct operation of the motion sensor depends not only on the correct connection scheme, but also from the place of its installation. Depending on the corner of the device coverage, mount it in such a place so that the area of ​​the action is possible in the action zone. If the input to the room is one, the sensor is installed opposite the input. If the input is two, the sensor is placed on the ceiling. In this case, the angle of the apparatus should be 360 ​​°. In addition, several more important rules should be observed:

  • In the area of ​​the device, there should be no devices that have electromagnetic radiation (otherwise interference can disrupt its operation);
  • the sensor should not be sent a flow of air from the air conditioner or fan;
  • The device must be as far as possible from the heating devices;
  • The direct light should not fall on the housing (if the sensor is installed indoors with the window, it is important to adjust its inclusion only in the dark).

The execution of the listed requirements will help to avoid false positives or, on the contrary, will exclude the displacement of the sensor when the lighting is required.

Tip: If your house has animals, and you want to avoid the triggering of the sensor when they appear in the action zone, select an optionally acceptable option. Either you will adjust the sensitivity of the sensor by setting the minimum value for triggering, or immediately buy a model with an animal ignoring function. Such devices do not respond to moving objects weighing less than 10 or 25 kg.

Connect the motion sensor

1698_DATCHIK_DVIZHENIYA4.Before viewing the scheme for connecting the motion sensor for lighting, it is necessary to disassemble it. Unscrew using a screwdriver the rear panel of the case - inside you will see a block for connecting the wires. It is worth noting that the installation process of this device is something similar to the setting of the switch. That is, an electrical circuit is performed with the luminaire successively on it, and the sensor closes or opens this chain, including or turning off the lighting. And in fact - there is nothing complicated in the process. First, on the block there are notations for connecting the wires: n - zero wire, L - phase, L with an arrow (or a) - a terminal for connecting to the lighting device. Secondly, the Motion Sensor Connection Scheme shows on the device housing or in the instruction. You just need to select the optimal installation method. We will describe the two most common.

Option 1: Connection through the lighting device. This is a fairly simple and convenient way that does not require access to the junction box. Great for those places where a person is short-time: on the porch, the landing, in the storeroom, etc. The device here works as follows: the light turns on when a person appears in the zone of action, it burns some time, while there is a movement, and turns off when there is no movement. It is very convenient - a person does not need to press the switch, for example, if hands are busy.

Example Motion Sensor Connection Scheme for Lighting without Switch


How to connect. From terminal L directly to the phase conducted wire. From the C terminal N - zero wire, which also goes to the lighting device. From the terminal a wire goes to the lighting device

Option 2: Connecting through a switch. This method is slightly complicated, but in some cases it is considered more efficient. For example, the motion sensor is installed in the kitchen. A person comes into the room - the light turns on, the person sits down and does not move - after some time the light turns off. Agree, not very comfortable. It is for such situations where the light should burn without a constant movement of the object, you need an additional possibility of controlling the lighting - setting the three-position switch.

Sample Motion Sensor Connection Scheme for Lighting with Switch


How to connect. From the terminal N, as in the previous case, the zero wire is moving into a junction box to zero conductor. There is a layout on the lighting device. From the terminal L phase wire goes to the three-position switch and connects to the terminal, which is responsible for the average key position. It is in this position that the lighting control will be carried out by a motion sensor. From Terminem A there is a third wire that connects the motion sensor and the lighting device. In turn, from the lighting device, a wire to the terminal with the top key is locked. In this case, the lighting control is carried out using a switch. The lower position of the key is light shutdown

Fresh sensor

1698_DATCHIK_DVIZHENIYA3.After making the installation in accordance with the Motion Sensor Connection Schedule, you should collect the instrument housing and fasten it on the wall or ceiling. In the selected place, drill the hole (or two - depending on the method of fastening the housing), insert the dowel there and secure the device using self-tapping screws. If the housing is swivel, send it to the intended zone of action. Ready - It remains only to configure and test the device.

Perform configuration

Standardly, the motion sensor has three regulators: illumination, time and sensitivity. With their help, the instrument is set to correctly respond to almost any operating conditions. Setting up most models identical. It is important that it is done when the light is turned off. The sensitivity controller should be rotated until it stops clockwise, and the time controller - until it stops counterclockwise. To configure testing, the sensor may take about a minute. After that, follow the check: exit and enter the room or in the sensor action zone, if installed on the street. The sensor must include the light and turn it off. It is important that over 5 seconds passed between the tests. After that you can customize the sensitivity and response time as you need. Turn the regulators and test - by the method of trial and error you will definitely select a comfortable sensor mode for you. Detailed configuration guide you will find in the instructions and can cope with this task.

Be sure - the correct installation and configuration, as well as a suitable scheme for connecting the motion sensor will get rid of you from problems during operation. The light will turn on when you appear in the device area and disconnect as soon as you leave it. This is the principle of correct operation of the device, which serves for convenience and savings. You can reduce electricity consumption by 50 - 70%. If you are interested in the possibility of installing the sensor with your own hands, you can buy it in our online store now.

Wiring Tips

The owner of housing can significantly improve the comfort of lighting control in the house by setting the sensor automatically turning off and including a light bulb. Consider the procedure for installing such equipment, possible connection schemes and other concomitant moments.

Principle of operation

Motion sensor allows you to automatically manage the switching of the electrical network. The principle of the detector is assumed to trigger if the degree of illumination decreases below the value provided.

principle of operation

The device catches the fluctuation of the waves in the infrared range, responding to a moving object, entering the element field. Settings are assumed to adjust the duration of the device.

Externally, the sensor is made in the form of a plastic box with an open film with a frenzel lens that tracks enter the influence of the device of a moving object into the zone.

Also designed sensors that are triggered from ultrasound and microwave principle.

Types and price of sensors

Different types of devices that differ in terms of application and design features are offered. Depending on the operating conditions, the following varieties of these items are distinguished:

  1. Street - Used outside the house. They differ in a wider range of 100 to 500 m. These devices are suitable for installation at the local area.
  2. Indoor - Installed indoors. Such devices are not designed to operate in a significant temperature difference and environmental humidity and should be used indoors.

Depending on the principle of operation, the devices operating in the following principles are distinguished:

  1. Ultrasound - Customizing the waves of the corresponding spectrum.


  2. Infrared - Determining the degree of illumination.


  3. Microwave - Functioning on the principle of the radio locator.


The cost of the specified equipment ranges from 400 to 900 rubles and higher, depending on the following factors:

  • type
  • characteristics
  • Prestiges of the manufacturer,
  • Conditions of application.

The most expensive from the presented are microwave, implied street use.

Advantages and disadvantages of equipment

The use of these automatic elements allows the user to achieve the following advantages:

  • Improving the level of comfort - lighting control is performed automatically, without user participation;
  • saving energy resources;
  • The possibility of obtaining additional options with one device - the sensor can signal the appearance of a third-party object, the emergence of a fire and other situations.

Disadvantages are related to the need to purchase additional equipment and complications of the home electrical network scheme.


How much will the electricity sensor consume

The level of energetic energy consumption by these devices is very insignificant. Depending on the characteristics of the device, it can spend from 0.05 to 5 kW * h. But its use can significantly reduce the amount of energy consumption, which compensates for the additional consumption by the instrument itself.

How to choose the sensor

Equipment should be purchased, taking into account the following points:

  • Application conditions - depending on the installation on the street or in the room;
  • The location of the device is determines the requirements for fastening and type of equipment;
  • viewing angle - if the device will control the input and output, it is enough to 180 °, for ceiling devices will require circular access sphere;
  • Time settings - This question is especially relevant if the devices are installed in large rooms while using multiple devices.

It is also necessary to take into account the financial capabilities of the owner to choose a device with sufficient characteristics, simultaneously arranging the buyer for the price.

Schemes and Sensor Connection

The sensor can be connected according to various schemes, depending on the terms of use and tasks. Consider detailed possible connection schemes.

With switch

If the device is connected to the switch, the following scheme applies:

with switch

This method is convenient when you need to exclude the spontaneous turning off the light, if the person is in the room, without moving. In this case, a triple switch is applied.

Connection is carried out taking into account the following points:

  • zero wire from the junction box is divorced to the sensor and to the lighting device;
  • phase wire - to the corresponding switch of the switch at its input;
  • The second contact of the sensor is summarized to the middle terminal of the switch;
  • The lighting device also connects to the top terminal of the switch.

In this case, the light control is made using a switch.

Without switch

Possible simpler diagram, without using the switch:

without off

For connection it is necessary:

  • From zero wire in the junction box, connect the sensor and the lighting device;
  • The phase wire is supplied to the lighting device through the sensor, by analogy with a conventional switch.

In this situation, the sensor only controls the inclusion and shutdown of the lighting.

Scheme with starter or contactor

The use of a starter and contactor scheme is necessary if equipped with a capacity of more than 1 kW, which is not often found at home:

with contactor

In this situation, the current is fed through the starter, and the sensor is controlled by the contact coil. The output on the sensor is connected to the coil, with the union of zero wires.

Connecting two sensors

With a complex room configuration, several lighting devices can be installed in the room, with the need to separately turn on and off. In this case, several automatic devices connected according to the following scheme can be installed:

With 2 sensors

The principle of instruments involves the following:

  • When entering a long corridor, the light turns on;
  • when approaching the second sensor, the next source is turned on, without shutting down the previous one;
  • When turning over the angle, the next sensor is triggered, without turning off the rest;
  • When the corridor is abandoned, the light turns off.

The number of devices is not limited and depends on the conditions of the room.

Connection Schemes for Trip Conductive Network

Three-wire scheme

Setting and testing sensors

After installing the device, you must configure it to ensure proper work by following these steps:

  • The regulator on the device case is set to the degree of illumination to trigger; adjustment
  • Using the second regulator, the duration of the shutdown delay is configured;
  • An angle of rotation is established, depending on the zone that should be covered.


After completing the setup, the instrument is tested by testing. If individual parameters do not suit the user, additional regulation is required.

Problem problems or connection errors

The use of motion sensors for lighting can be associated with the following problems caused by a malfunction of the equipment or errors during the connection:

  • Incorrect phase and zero - from the point of view of security, the device is connected to the gap of the phase wire, by analogy with the switch;
  • false positive - if the sensors are incorrect or unexpected factors are affected in the form of thermal radiation, tree branches, etc.;
  • unfounded inclusion immediately after the disconnection - when the lamp is directed to the device or other light source;
  • improper use - when installing a wall instrument on the ceiling or the use of an outdoor room;
  • The influence of glare and air flows - draft or reflection of the sun rays can cause spontaneous triggering of the element;
  • Damage or contamination of the sensitive element - as a result, the sensitivity of the device is reduced.

To avoid malfunctions, the installation of the device should be engaged in a qualified electrician. The device should be checked before purchasing to eliminate the presence of visible defects. Connection must be implemented strictly according to the scheme.

The use of sensors of automatic lighting control allows the degree of home comfort to a new level. But it is necessary to choose correctly and install the device to eliminate possible problems.

How to connect the motion sensor to the light bulb

What do you need a motion sensor for lighting

As a rule, the term "motion sensor" in everyday life is determined by an electronic infrared device, which allows you to detect the presence and movement of a person and helps to switch the power of lighting devices and other electrical appliances.

If you want to make your home safer, buy motion sensors that will not only be convenient assistants for you, but also help save electricity, including or turning it off at your inlet or outlet out of the room, respectively.

The motion sensor has a simple principle of operation - when motion appears in the zone of its sensitivity, all devices connected to it are connected. Turning off all devices occurs when the circuit is automatically blurred, and this happens in the absence of motion. In this article, we consider in detail Motion Sensor for Ultralight ASK 1403 Lighting having an angle of review 180 gr.

Typically, the motion sensor is used to turn on the light, but these devices can be used and not only for this purpose. I want to note that there are sensors with a viewing angle by 360 degrees.

That is, the sensor is able to detect any movement from either side. Therefore, if you have a store, an office or any object that you need alarm, then in this case a security alarm can be used.

Motion Sensor Connection Scheme to Lamp

Connecting the motion sensor is a simple process that has many analogies with a conversion of a conventional switch. After all, as the switch, the motion sensor closes (or opens) an electrical circuit with a sequentially turned on with a lamp, which is the similarity of the sensor connection schemes and the lamp by the switch.

By purchasing the sensor, you must also get the standard instruction for installing, configuring and connecting. Another option to study the scheme is to view it on the device itself.

Under the back cover there is a terminal block, as well as three color wires connected to it, which come out from the inside of the case. Wiring is connected to terminal clamps. If you use a multi-core wire to connect, then it is better to use special insulated NSHVI tips.

Next, we will tell about the features of the concept of connecting the motion sensor.

Power on the sensor from the network comes along two wires: phase L (brown wire) and zero n (blue wire). After the phase output from the sensor, it comes to one end of the incandescent lamp. The second end of the lamp is connected to zero wire N.

In the event of a movement in the control zone, the sensor is triggered, and then the closure of the relay contact, which leads to the arrival of the phase on the lamp and, respectively, to the inclusion of the lamp.

Since the terminal block for connecting has screw clamps, we connect the wires to the sensor with the help of the tip nsw.

It should be noted that the connection of the phase wire is best to produce in accordance with the schematic diagram that complements the instructions.

After the wires are connected to wear the lid and go to the next step - connecting the wires in the distribution unit.

Seven wires enter the box, three from the sensor, two from the lamp and two feed phases and zero. In the feed cable, the phase has a brown colors, zero - blue.

We deal with wires. The cable that is connected to the white wire sensor is a phase, green is zero, the red must be connected to the load.

Connecting the wires occurs in about the way: the phase power cable wire is connected along with the phase wire from the sensor (brown and white wire). Then connect together the zero wire from the feed cable, the zero wire from the sensor (the one that is green) and the zero wire from the lamp.

There are two unused wires (red from the sensor and brown from the lamp) - they connect them together. All connection is ready, as you can see anything complicated.

Showing closer how to connect the motion sensor in the box . I think to deal with the connection will not be much difficulty (if not, then write in the comments we will disassemble). Now you can feed meals.

Motion sensor is connected to the lamp. After that, we feed the power, the sensor reacts to the movement and the closure circuit includes a lamp.

Is it possible to connect the sensor with the switch

It often happens that the motion sensor must be connected to the lamp along with the switch. It would seem two devices that are intended for almost the same task - to include lighting.

Really, the switch turns off the lamp (lamp) and the motion sensor under certain circumstances (motion detection) performs the same task - it supplies power to the lamp. Why these two devices connect together, many do not understand. So let's understand How to connect a switch with a motion sensor And why do it?

If you want you to have a lighting, regardless of the level of time, regardless of the level of time,, regardless of the level of illumination and movements, try apply Sensor Connection Scheme with Switch By connecting a regular switch with one key to the diagram parallel to the sensor.

Thanks to this connection, you can with the turn on the switch to hold the lighting on during the desired period of time. At the same time, the lighting control must completely go to the sensor, for which the switch should be turned off.

Connecting the motion sensor with switch - how to do it and why?

The switch that is connected in parallel to the sensor can be added to the scheme for the permanent operation of the lamp in the room, regardless of whether or there is no movement in the room. In this case, the switch can duplicate the operation of the motion sensor, as a result of which it will be forcibly controlled lighting.

I will tell my situation for which I need Connect the switch with a motion sensor . I live in a private house and often come home late in the evening in the dark, especially in winter, when it gets dark.

For this I installed Motion sensor for lighting Directed at the inlet gate in the yard. That is, when I go to the courtyard in the evening, the sensor must work and turn on the lighting. And the sensor I set up so that the lighting worked such a period of time is sufficient to walk from the gate of the door to the door of the house.

Now imagine that I need to get out of the house in the courtyard or at night, well, for example, in the store or say, I will hear some rustle in the yard, but there is no lighting (by the way the sensor covers not the whole courtyard). For this, I need to go out in dotmakes and wave your hands while the sensor does not work?

That's why I had a need Connect the switch with a motion sensor . And when I get out of the house to the yard, I just turn on the switch and the lamp is lit without depending on the sensor. Connecting the motion sensor with the switch is absolutely not difficult.

Now the diagram in which the switch with the motion sensor is connected together but the lamp is running from the switch (regardless of the sensor).

Setting the motion sensor for lighting

Setting the motion sensor - This is another important nuance of this device. Almost every sensor, with which you can control the lighting, has additional settings, allowing you to achieve its correct operation.

Such settings have a kind of special potentiometers designed to adjust - this is setting the TIME disconnection delay, adjusting the LUX light threshold and the sensitivity sensitivity regulator to the infrared radiation "SENS".

1. Time setting - "Time"

Using the "Time" installation, you can set the time during which the lighting will be included from the moment when the movement was found for the last time. Setting the value may vary from 1 to 600 seconds (depending on the model).

The "Time" regulator can be set a setpoint to expand the time of the motion sensor. The limits in which there is a trigger setting, range from 5 seconds to 8 minutes (480 seconds). The speed of the person in the sensitivity area of ​​the sensor plays the most important role here.

With a relatively rapid passage of a person of this space (for example, a corridor or staircase in the entrance), the setpoint "Time" is desirable to reduce. And, on the contrary, when founding within a certain time in this space (for example, in the pantry, auto parking, utility room), the setpoint "Time" is better to increase.

2. Setting the trigger from the light level - "LUX"

The "LUX" adjustment is used for the correct operation of the sensor during the daytime. The sensor will work when the movement is detected at a lower level of ambient light compared to the threshold value. Accordingly, the triggering of the sensor is not fixed at a higher level of illumination as compared to the installed threshold value.

The drawing is depicted how to set up the motion sensor with your own hands . To configure on the reverse side of the sensor there are three regulators: a trigger sensitivity regulator, a time regulator and a light controller. Experiment and everything will work out.

The "LUX" regulator is set to a response setting over the level of environmental illumination (from twilight to sunlight). The division of the scale on which you can put the "LUX" setpoint, if there is a large number of windows and the predominance of natural lighting, should be minimal or medium.

Put the "LUX" setup for the largest division of the scale is recommended if there is natural light in your room or with a small amount.

3. Setting sensitivity to the triggering of the sensor - "SENS"

Adjust the sensitivity to triggering, depending on the volume and range of the object, can be used using the "SENS" regulator. The sensor response to motion directly depends on the level of sensitivity. With a very large number of sensor triggers, sensitivity is desirable to reduce, and configure the brightness of the Illumination of the IR to which the motion sensor should react.

Increase sensitivity follows when there is no response to the sensor. With spontaneous turning on lighting, you can reduce sensitivity. If the sensor setting was made in the winter season, then it is quite likely to reconfigure it in the summer, and, on the contrary, it will be necessary to reconfigure during the summer setting.

And last, only by setting up the controlled zone, you can get a guarantee that it will "see" you. To do this, adjust the optimal position of the head of this sensor. Here will be sufficient to check the reaction of the sensor to move in some point located in the distance.

Installing the motion sensor to the lighting chain. Selecting a Place for Sensor

If you are interested in the question of how to connect the motion sensor correctly, then you have discovered the desired article. After examining the material presented below, you will understand that the connection is practically similar to the installation of a conventional switch, and the main difference between them is the principle of operation - mechanical and automatic.

Infrared Motion Sensor - Photo 01

Immediately several recommendations

At the beginning of the article I would like to give you some tips and tell you what to avoid when connecting the motion sensor:

  • First, any obstacle in the visibility zone can affect the false triggering, which will lead to unnecessary inclusion of lighting (we are talking about trees, bushes, etc.)
  • Certain work may prevent any sources of heat and electromagnetic radiation (do not install the sensor opposite other devices emitting light)
  • It works under a certain angle and will only work in the direction in which
  • Try to follow the cleanliness of the motion sensor, as the dirt on it can lead to a deterioration in the quality of work or a decrease in the radius
  • The lighting sensor for lighting is not designed to work at high loads, since the average power of such usually ranges from 500 to 1000 W, so pick up the lighting devices by power

Motion Sensor Connection Scheme - Photo 02

Connecting one chain motion sensor

To begin with, you will learn how to connect one movement sensor in the chain. It has three terminal clamps. From one clamp, the wire is carried out directly to the phase, the other terminal is designed for zero wire, and the third is to connect the lighting device. As you can see, the Motion Sensor Connection Scheme is quite simple.

Motion Sensor - Photo 03

Motion Sensor Connection Scheme - Photo 04

If you would like lighting to work constantly, even when there is no movement in the visibility zone, you need to connect the switch directly to the motion sensor in parallel. For this, the switch is connected from the phase to the part of the wire located between the motion sensor and the lighting device. When the switch is open, the motion sensor will work, as required, but if you close the switch, the lamp will work on the sensor bypass. Everything is simple enough.

Motion Sensor Connection Scheme - Photo 05

Connecting multiple sensors in chain

Now let's try to explain how to connect the motion sensors if there are two or more. And this requires if the radius of the action of such a sensor is too small and it lacks it to cover the necessary territory.

Connecting multiple sensors in chain - photo 06

Connection diagram of multiple sensors in chain - Photo 07

It is necessary to select a place to mount the sensor so that it opens the highest angle of the review. But in the premises of chaotic layouts, it is almost impossible to carry out this using one device. In this case, the sensors are connected in parallel to one phase! If you connect sensors to different phases, then be prepared for the appearance of short circuit due to the interfacial connection.

Place for mounting

Even if you have found a motion sensor schema for lighting, choose the best place to install is not so simple. You must immediately take into account several factors affecting the quality of its work. So, it should not be installed near the heating systems, air conditioners, sources of electromagnetic radiation (microwave, radios, televisions).

Motion Sensor Location - Photo 08

Before you choose a place, you need to decide exactly how the motion sensor for lighting will be connected to the network. Motion sensors operate either from the voltage of the network 220V or from the battery. Movement sensors operating from the central network are more common. They can be connected either through a box, or with the help of wires that come from the chandelier.

The second option is more acceptable due to the fact that often the boxes are hidden under the wallpaper and even if you find them, then without professional skills and knowledge to understand which wires you need is very difficult. Therefore, to connect the motion sensor we recommend from wires going to the chandelier.

On practice

Suppose you need to connect the motion sensor for lighting in the bathroom. Surely you have one lamp there and it is located on the wall. Motion sensor for lighting is best placed under it.

On the other hand, if the motion sensor is located on the street or indoors, where in the daytime day the number of sunlight falls, then you need to take care of the sensor setting. The sensor has several regulators that can be configured: response time, light level, noise level and sensitivity (allows you to adjust the range). Set the sensor so that it does not work with strong lighting.

Motion Sensor is located next to the lighting source - Photo 09

In practice, connecting the motion sensor should be started from its inspection. On the box (usually under terminals) there is a diagram of connecting the motion sensor. Terms three and have them the following notation: L, N and L with the arrow. The usual L denotes the terminal to which the phase is connected. N is a zero wire, and l with the arrow - the wire for connecting to the lamp.

Connection Scheme Lighting Sensor through Junction Box - Photo 10

Pay attention to the wires coming from the wall to the chandelier. There are two of them. Clean the wires and connect the terminal block of three pieces. Motion sensor scheme for lighting is simple: through the upper terminal of the chandeliers, swipe the phase and close it on the terminal of the sensor, indicated by the letter L. Through the middle terminal of the chandeliers, swipe the zero wire and close it on the sensor terminal with the designation N.

Through the middle terminal, the chandeliers pass two more wires. One wire is connected to the chandelier, and the other to the second outlet. The phase wire from the sensor terminal goes to another terminal not directly, but through the open relay. The terminal with the letter L and the arrow on the motion sensor is connected to the third chandelier block terminal. To the lower terminal, the chandeliers are connected to the light bulb and an additional outlet. The relay will be triggered when the motion sensor locks any oscillations. As you can see, connecting the motion sensor for lighting is simple.

Selection of traffic sensor connection schemes for light

A person came up with a huge amount of electronic devices designed to protect his life and property. At the same time, a convenient and reliable means to date is a motion sensor to turn on light, there is no scheme for enabling device data depending on the parameters of the controlled room.

The lighting sensor for lighting responds to the appearance of a large object in the zone of propagation of its rays or waves, depending on the technology applied in the device. The first models of these electronic assistants were initially used to improve the quality of protection of production facilities. Today they are used almost everywhere and not only to ensure the order, but also as a convenient means that allows no extra action to include lighting, thereby ensuring comfortable conditions for moving. The motion sensor used to turn on the light responds to the appearance in its sensitive zone of a person or a large animal. The reaction to the appearance of the object is the switching power circuit.

Motion sensor use options

In addition to the lighting devices, the motion sensor can also be used to include other means of alert. It can be a sound beacon or a central alarm system. When complementing the security complex, the sensor is mounted at the most important entrances to the building or in the corridors. You can also use the sensor as a switch to turn on lighting in dark rooms where the lamp is constantly required.

It is much easier and more convenient to automate the process. The sensor when the man's action zone appears automatically lock the lamp power circuit and after the object is careed from the zone - will turn off. Depending on the modification, the sensor can be configured to delay the moment of disconnection after the disappearance of a person from 10 seconds to 7 m. This will not only provide comfortable conditions for movement, but also saving electrical energy, because the light will burn only when a person is in the radiators and receiver.

Functionality and features of the motion sensor

Before you know how to establish a light motion sensor, you must familiarize yourself with its capabilities and varieties. This will make it possible to understand which principle it is necessary to apply when making the installation of a type or another.

Depending on the installation site, the sensor is divided into:

  • perimetric - received use as a means of control of extensive territories, in particular, streets;
  • peripherals;
  • internal.

By way of action on:

  • ultrasound;
  • microwave;
  • infrared active;
  • Infrared passive.

By type of signal, sensors are divided into:

Depending on the functionality, the sensors are divided into the following types:

  • Universal or multifunctional. Used not only to determine the movement in the controlled zone, but also determine the need for inclusion. If the light level corresponds to the specified value, the lamp does not turn on if not, then turns on.
  • Indoor. It is used mainly to monitor activity in the room, working as part of the alarm system. Answer alert activation.

How to install a light motion sensor

Installation of the motion sensor To turn on light can be performed in several ways, which depends on the design of the room or some requirements from customers.

Depending on how to put the device, they are distinguished by the following types:

  • Overhead. The sensor is mounted on the wall.
  • Ceiling. The control device is installed on the ceiling, lighting can be integrated with a light motion sensor in a single housing or located directly near the lamp.
  • Mortise. Installation of the device is performed by embedding in the wall, the main purpose is to detect activity in office space or residential rooms.

Options for switching on the motion sensor

There are several options for switching the motion sensors to turn on light. The choice concrete lies at the customer. This is due to the fact that the sensors can be different, that is, with a different contact group. Not through all models of devices, you can switch instruments with high current consumption, for example, spotlights with glowing lamps. In this case, it is better to use the starters as intermediate commuting components, and to increase the reliability of the presence control system, use different types of sensors, combining their inclusion schemes. For example, ultrasound and infrared.

If we consider the models of the sensors, depending on the production technology and the principle of operation, then this can be both ultrasound or microwave and infrared. But it should be remembered that the first two types of sensors have a built-in high-frequency generator, which can be excited due to different interference and powerful electromagnetic waves. Therefore, it is necessary to install them in distant places from all of these factors. It can be storage facilities, checkpoints and more.

For home use or in conditions with plenty of interference, sensors with infrared emitters will be more suitable. It can be used both active and passive.

Generalized Motion Sensor Inclusion Scheme

The simplest movement sensor inclusion scheme includes only a few components:

  • sensor;
  • connecting wires;
  • Lamp or audio operating system.

Almost all sensor models have a single constructive device, which is a housing, a contact block, scattering the sphere or glass. The sensor itself has only 3 contacts, so there should be no difficulties with its electrical connection. Moreover, in virtually each model is attached installation and settings.

The figure below shows the simplest scheme for switching on the motion sensor consisting of the sensor itself and the lamp. Installing such a sensor can be performed in almost any convenient location.

Important moments when performing a connection for this scheme is the observance of the polarity of the wires. The phase wire from the AC voltage must be switched through the sensor on the lamp. It is necessary to pay attention to the color. As a rule, blue - zero, brown - phase, red - switch outlet. Coloring may differ from different manufacturers, so it is desirable to use a phase indicator or other devices. As the latter, you can use not only the lighting device, but also the sound alarm. When installing a powerful searchlight with a consumption of more than 0.5 kW, it is recommended to use an intermediate starter and install it in a separate mounting box. This is necessary to eliminate the extension of contacts at the moment of switching low-volume load.

Combining Motion Sensor with Switch

To ensure the permanent operation of the lamp, regardless of the level of illumination and the presence of a human sensor in the zone, a switch can be put in the circuit. A single-wave type switch can be used. When it is turned on, switching sensor contacts are shunting, which ensures permanent lighting mode.

It is important to remember that in order to implement the sensor on this scheme, it is necessary to strictly monitor the colors of the wires to prevent unexpected short circuit.

The neutral or zero wire from the switch should be directly directly to the lamp (lamp) from the network, the phase wire passes through the switch, which is parallel to the switching group of the sensor. If the starter is used in the schema, then its winding should be powered by a switch.

Multiple Sensor Connection Scheme

The diagram of the first type was widely used in simple form rooms. It may be a square, a rectangle or a circle, in general, where only one specific zone is required to control. If you need to organize an automatic switching on the illumination in the rooms of a complex form with additional branches and bends, for example, in curved corridors, then you need to apply several sensors. But in this scheme also has its own nuances. For example, if you need to organize the comfort of movement along a long corridor, but it is necessary to ensure maximum savings, then the sensors must be turned on independently of each other, that is, in parallel.

If you want to create a reliable security system, then connecting the motion sensor to the light should be performed according to the scheme shown below.

Here the sensors are combined with a phase wire from the network. Zero wire enters all sensors and lamp or signaling without intermediate switching. It is important not to confuse the colors of the wires and control the phase on all devices so as not to create a short circuit in the diagram. When you trigger any of the sensors, turn on the main signal lamp or sound alert system.

When creating a system with controlled luminaires parallel to the sensor contact group, a switch is set. If the scheme consists of several motion sensors, and it is required to provide an independent inclusion of each of the lamps, the switch is installed on each sensor.

Before checking the movement control device, you should verify the colors of the wires and the reliability of their clamp in the terminals.

How to properly install light switch motion sensor

How to properly install a motion sensor that responds to light so that the system worked securely without false positives. First of all, it is necessary to determine the parameters of the room. It is important that the sensor overview angle is maximum and covered the large area.

If the coating zones of one sensor are not enough, then several of them are used. At the same time, they are installed in the corners of the curved room of the wrong shape. The installed sensor should not intersect with its controlled zone with adjacent. In addition, it is important to remember both the installation rule so that the false triggering of the sensors does not occur: in the zone of the sensor, there should be no sanitary pipes, power and high-frequency cables, trees and shrubs.

To properly mount the lamp with a motion sensor or a separate sensor, you should pay attention to the instruction that is included with each sensor. As a rule, manufacturers represent various installation options and their combinations in order to ensure the best performance indicators.

When making the installation of motion sensors on the street, you must use protective terminal boxes. The sensors themselves should be securely hidden under the visors of the buildings and are protected from snow or rain.

Setting the motion sensor for lighting

There are several varieties of sensors on sale depending on the functionality. Of these, you can allocate:

  • Simple. Used only to switch the luminaire power circuit in constantly dark rooms that respond to movement in the controlled area.
  • Universal. Adjusts the operation time after automatic switching on (TIME), the sensitivity threshold in infrared sensors (SENS) and the moment of inclusion at a certain illumination level (LUX). Setting the motion sensor for lighting can be carried out from 10 seconds to 7 minutes, which is usually required on the staircases. The highlighting scheme of the stairs with a motion sensor in this case is no different from the above.

Adjustable sensor allows you to provide better electrical energy savings and provide the most comfortable conditions for moving around the room depending on the level of illumination.

How to connect the motion sensor to the light bulb. Connecting the motion sensor: scheme

Today, few people can surprise various innovations used in the arrangement of residential premises. For quite a long time, the use of such a device is practiced, which is responsible for the inclusion and turning off the light when the person appears. Despite the seeming complexity of such equipment, it can almost everyone can make it yourself, for this you only need to know all the nuances of this work and carefully fulfill all the recommendations on the installation.

Therefore, it is necessary to consider in more detail how to properly install and connect the motion sensor for lighting, as well as deal with the features of the design of such an instrument.

Scope of Motion Sensors

If you used to purchase this device, it was possible only for very much money, then today almost everyone can afford to have similar equipment at home.

Its installation is carried out, as a rule, in the entrances of residential buildings, in private facilities, as well as at various enterprises, which provides people with additional comfort and safety.

The main purpose of the motion sensor is the inclusion of the lighting device when a person appears. At the same time, the automation is triggered responsible for actuating the entire system. Moreover, such a mechanism can be responsible not only for the inclusion of light, but also sound, alarm, etc. But then it will discuss how to connect the motion sensor to the light bulb. This is primarily due to the fact that this version of the device was widely distributed among the population.

Technical features design

Tracking movement becomes possible and thanks to the infrared radiation beam located inside. In addition, the housing is also equipped with special legs-hinges, thanks to which you can change the position of the device.

The sensor can be recorded both on the wall and with the help of a special auxiliary bracket. Sometimes on the housing there can be a button on and off, but there are samples and without it, it all depends on the specific model and the type of equipment used.

Types of motion sensors for lighting

To deal with how to install the motion sensor, it is necessary not only to examine the information on its installation, but also select the desired sample, since there are several categories of such equipment. So, there is a division of these mechanisms in accordance with the installation site and according to the type of signaling device, but the two largest groups are sensors for the street, or exterior, and for the room (internal).

The principle of operation of samples for the street is based on the calculation of the distance from the device to the object. This option will be convenient for private houses with a large territory, as well as massive structures of an administrative and economic nature. Some models for quality work require a searchlight, which is important to consider when installing.

The room sensor can be connected to any of the rooms, but when used it is important to ensure that the microclimate is more or less stable, that is, without sudden temperature drops, otherwise the device can simply fail.

In addition, this equipment can be divided into the following categories:

  • Ultrasonic motion sensors for lighting. Function by reflection from the surrounding objects of ultrasound. This option is available in price, it is durable and easy to operate.
  • Infrared devices. The principle of their action is based on sensitivity to temperature change. This means that when in the radius of its coverage of waves with a specific heat indicator, light lights up automatically, and you can always set the desired parameter so that the mechanism does not work, for example, when an animal appears.
  • Microwave sensor is identical to the standard locator. A signals having a certain frequency are periodically transmitted to the device, as a result of which, after their capture, the device is turned on. Such samples have some similarity with ultrasound instruments, but their cost is higher.

Advantages and disadvantages of equipment

In order to understand how to properly connect the motion sensor to control the light, of course, it is required to study all the positive and negative sides of such an instrument. And already based on this data, it is worth installing it or not.

The advantages of this popular and convenient mechanism are considered as follows:

  1. Low power consumption. Thanks to this sensor, you can not be afraid to forget about the need under any circumstances to turn the light, since this problem is solved automatically.
  2. Comfort operation. The use of this equipment will avoid long searches of the switch in the dark.
  3. High level functionality. These devices are completely able to do without wires, which makes them use more convenient.

Nevertheless, such equipment has two main disadvantages:

  1. High price, as a result of which its installation can afford not all.
  2. Relatively complex installation process. The most important elements in solving the question regarding how to connect the motion sensor, the instruction and scheme. Installation provides for certain skills to work with similar equipment, otherwise it will be more correct to seek help from specialists.

How to determine the place for mounting the device?

It is extremely important here to remember that it is impossible to mount the sensor near the radiators of the central heating of the pipeline, next to the air conditioners and electromagnetic devices.

If the equipment is connected in the wrong place, it can even react even to minor fluctuations like the shaking of trees or movement over the perimeter of the house. Therefore, it is necessary to choose a suitable area where there will be no thermal or other impact on the device, and within the zone of its coverage will not be extraneous objects that can affect its work.

Setting the motion sensor for lighting

Any technical equipment used in everyday life requires pre-configuration. Therefore, if the question occurs regarding how to establish a motion sensor, it is initially necessary to adjust its mechanism so that it worked as accurately as possible.

Usually, the connection of these devices is performed directly to the network of electricity with a standard voltage in 220 V. Make this not only in the case of radio models, the work of which is based on the use of the battery.

In order to facilitate the wizard such a procedure as connecting the motion sensor, the scheme for its installation is usually displayed directly on the surface of the device in the area of ​​the block for terminals.

So, tested whether the equipment functions, you can, paying attention to its indicator. If it burns, it is not worried about what, but if not, then you should configure the device otherwise. As a rule, not only the flashing itself, but also its frequency, which increases with the occurrence of a person in the zone of its radius of action.

The housing of any of the devices is usually equipped with special adjustment handles, thanks to which it is much easier to adjust the work so that electricity is consumed in a minimum number in the afternoon, it becomes possible to establish a range of sensor coverage and so on.

Tools for self-assembly motion sensor

  • solid housing (the base from the old camera is suitable);
  • Base of control of elemental type (can be purchased in specialized stores);
  • screws;
  • wires;
  • soldering device;
  • screwdriver.

Further, all functional parts of the future sensor are required to collect, while many owners have a question: "What is the optimal motion sensor connection scheme?" In order for the design and connection of the device, it is necessary to take into account the features of the device, its technical characteristics and, of course, the correct connection algorithm. Therefore, it should be sown in more detail with such installation instructions.

Mounting scheme device

Connecting the motion sensor for lighting

By solving the task, how to connect the motion sensor to the light bulb, the following rules for their installation should be taken into account.

It also happens that it is necessary to install several similar mechanisms in a row, for example, in stock. The scheme of their device is similar, but in this case the wires should be located around each of the lamps separately. Alternatively, the main wire can go in a circle from the switch, while the lamps will be connected to it with a chain. In this case, the installation of the sensors is carried out both between the input wires and the outlet of each light bulb.

To install the most securely as possible, the room must be de-energized, the wiring must be cut in those places where the sensor wires will be connected, which, in turn, must be cleaned and twisted together. At the end of the work, it is important not to forget to carefully closer each of them insulating tape.

Recommendations for the installation of motion sensors

It is important to remember that the installation of any of such devices requires an individual approach, since the connection instruction can be different, but the main thing here is to equip the device in the place where foreign signals will not affect its operation.

When reasoning on the topic: "How to connect a motion sensor (light on) yourself," the following tips should be taken into account:

  1. For mechanisms with wires, it is necessary to carefully select the installation site, as such devices should not be carried out often from one place to another.
  2. It will correctly mount an additional switch, while both devices can function separately from each other. This will allow you to extinguish the light in the standard way.
  3. Premises with designer design is best equipped with a mortise alarm that perfectly fit into the interior.
  4. Before purchasing the sensor, you should seek help to a consultant with a question as to which a range of work should have a device in a particular room. A good solution will be the connection of the ceiling mechanism, a practically inconspicuous eye.
  5. It is important to prevent direct sunlight on the device, otherwise the device may soon fail.

Following all these recommendations, you can save yourself from many difficulties. That's all. Now you know how to connect the motion sensor to the light bulb. And these knowledge will help you correctly make installation and provide equipment quality work for a long time.

Motion Sensor Connection Scheme for Lighting

Motion sensor is an infrared electronic device that makes it possible to detect the presence and movement of a living being and helps connect the power of lighting devices and other electrical devices.

As a rule, the motion sensor is used to include lighting devices, but they can also be used and not only for this.

Types of motion sensors

At the location:

  • perimetric - apply to street lighting;
  • internal;
  • Peripherals.

According to the principle of operation:

  • Ultrasound - react to high frequency sound waves;
  • Microwave - high-frequency radio waves;
  • infrared - apply heat radiation;
  • active - there is a transmitter and a receiver of infrared radiation;
  • Passive - transmitter is missing.

By type of triggering:

  • thermal - react to changes in temperature at the point of response;
  • sound - work on a pulse when air fluctuations from sounds;
  • oscillatory - react to the change of the external environment and magnetic field when the objects move.
  • single-position - presence of a receiver and transmitter together in one block;
  • Two-position - transmitter and receiver are used in different housings;
  • Multiposition - two or more block with transmitters and receivers.
  • Multifunctional sensors Apply when determining movement and level of lighting indoors;
  • Room sensor is used for monitoring and control systems;
  • The outer illumination sensor is used to measure the degree of external lighting;
  • The overhead lighting sensor is designed to install on the wall;
  • The ceiling lighting sensor is installed in the suspended ceiling;
  • The lightening sensor is used to detect movement in office and residential premises.

Motion Sensor Scheme for Lighting

Connect the movement device is easy, it is not more complicated to connect the motion sensor to the light bulb. In both cases, the electrical chain closes or opens.

If a constant light is needed with the complete absence of any movement, you can turn on the switch parallel to its movement to the motion sensor.

Due to this, when the switch is turned on, the lighting will be turned on on another chain bypassing the device, since when the switch is turned off, control over the lighting state will be completely returned to the motion sensor.

Connecting multiple motion sensors

It often happens that the specific form of the room physically does not allow to embrace the entire area of ​​the room with only one device.

For example, in the curved corridor, if you set one motion sensor, then it will not work When the object will move bend.

In this case, use a device for connecting devices when several sensors are connected in parallel to each other.

In other words, the zero phase is not separate and not interrupted, it is supplied to each device, after connecting all outputs to the lamp. As a result, the triggering of any of these sensors closes the chain, feeding the voltage to the lamp.

With this joining you need to know that Both devices need to be connected from one phase Otherwise, a short circuit will occur between the phases.

Moreover, the technical conditions and design features of the room also have a direct impact on the connection.

Install the device is necessary so it gets like a larger viewing angle On the alleged areas of movement, it should not shield interior parts, as well as window and windows and doors.

Motion sensors have a long-permissible value of power at the level of five hundred and thousands of watts. This limits their use under high load conditions.

If there is a need to connect through the devices at once several powerful lamps, the best solution will be the use of a magnetic starter.

When buying a device, Included there must be a standard instruction By installing, connecting and configuring. Also, the scheme should be on the device itself.

Under the lid of the device there is a connecting block, as well as three color contacts connected to it, which are located outside the housing. Connecting wires produce to connecting clips. If a multicore cable is used to connect, then it is better to apply special NSHA's sleeve tips.

Features Sensor Connection Scheme

The current on the device comes from the network along two wires: phase L (brown wire) and zero n (blue wire). After the release of the phase L from the motion sensor, it comes one end of the light bulb. The other end of the incandescent lamp is connected to zero contact N.

When moving at the place of control The sensor is activated and the relay contact closes , leading to the arrival of the phase on the lamp and the light turns on.

Since the terminal block for connecting has screw clamps, the wires to the device are connected using NSHA tips.

You should know that the connection of the phase cable It is best to implement on a schematic diagram that complements the manual.

  • After connecting the wires, you need to wear the lid and go to the next step - connecting cables in the junction box.
  • The box has seven wires, two from the lamp, three from the sensor and two feeds zero and phase. In the feed cable phase is painted in brown, zero in blue.
  • The wire that is connected to the white cable is a phase, green is zero, you need to connect red to the network.
  • The wires are connected to about this: the phase feed cable is connected along with the phase wire from the device (white and brown cable). Next, connect the zero wire from the feed cable, the zero cable from the device (green) and the zero cable from the lamp.
  • Two loose cables remain (red from the device and brown from the lamp) - they are connected together. Connection performed.

Motion sensor is connected to the lamp. Then feed the power, the device reacts to the movement, closes the chain and includes light.

Is it possible to connect the device with a switch?

In order for some time the light is not disconnected, regardless of the degree of illumination and movement, you can Apply a device connection scheme with switch By connecting an ordinary switch to the diagram parallel to the motion sensor.

Due to this connection, when the switch is turned on, keep the light bulb on during the required time. If the lighting control must be fully transferred to the device, the switch is turned off.

Setup Device for Lighting

Device setup is another important step of the motion sensor. Almost any device, with which you can control lamps, has additional settings, which make it possible to achieve normal operation.

Such settings look like special mini-devices that are designed to regulate is to install TIME shutdown, regulate the degree of LUX illumination and an installation of susceptibility to infrared SENS radiation.

  1. Setting on the degree of illumination . LUX adjustment is used for correct operation of the device. The device will work at a lower degree of illumination compared to the minimum value. Hence, The sensor will not work at a higher degree of illumination. Compared to the threshold value.
  2. Setting time . Using the Time installation, you can set the time during which the lighting will be included from the moment when the movement was last detected. The time interval may vary from 1 to 600 seconds.
  3. Setting the susceptibility to the operation of the device . Adjust the susceptibility to the connection, depending on the volume and range of the object, you can using the Sens regulator. The device's response directly depends on the degree of sensitivity. With a large number of switching on the sensor, susceptibility is better reduced, and to install the brightness of the lighting of the IR to which the motion sensor will react.

Installation recommendations

In the scope of the sensor, which is installed on the street, objects emitting heat or light should not fall. Do not install the device near trees and bushes, which will interfere with the correct identification of movement.

Need to try to minimize The likely effect of electromagnetic radiation, due to which there may be false response of the device.

The sensor must be directed directly to the area where the identification of movement should serve as a reason for turning on the lighting.

It is necessary to maintain the sensor in purity, since pollution is negatively reflected on the quality of the device and the radius of action.

Comfort, ease of use and energy savings are three main advantages of one device. That is why we will tell how to connect the motion sensor to the light bulb. It is important that this procedure is simple, even a person who has no qualifications can cope with it.

Choose a place for mounting, the desired connection scheme, depending on the desired result, collect the electrical circuit and check its performance.

Motion sensor assignment - lighting

Motion sensor is a special electrical device that registers the presence of a person in the field of action and the supply electrical signal to the controller. The latter controls different devices, including lamps and chandeliers. The use of the element simplifies the operation of lighting devices, increases the level of security.

Motion sensor allows you to control lighting devices

The first detectors were used on large production and storage facilities, which pursued security goals. In recent years, the cost of detectors has decreased significantly, therefore products are more often used at home. Motion sensors are triggered automatically and a signal is fed to the controller of lighting and other devices, including alarm.

And yet in everyday detectors are more often used to automatically turn on and off lamps. In some cases, a parallel connection to the home security system is performed (a separate switch activating part of the chain is installed) - during the absence of the hosts of the electrician's house, protects their real estate from unauthorized access. The same is organized in the cabinets of directors and other important premises in enterprises.

Externally, the device is a plastic box of rectangular or round shape. The hole is overlapped with a matte film with Fresnel lenses. Inside the source of infrared radiation - the waves are fed through the window on the sensor. With their help, control over the presence / absence of a person on the territory controlled territory.

Motion Sensor with Fresnel Lens

Important! Fresnel lens is made of soft and gentle material, so in the process of installation, act as carefully in order not to damage the design.

Choosing a detector model

Before installing, select the model and functionality of the device depending on the targets, the size of the room and the operating conditions / trigger.

The devices are divided by the method of determining a person in the detection zone are passive and active.

  1. The principle of action of active resembles a standard radar - emitted infrared waves are reflected from the object and registered by Fresnel lens. There is a specified location of items by default - if it has changed, the sensor is triggered.
  2. Passive devices register the heat emitted by the human body.
  3. Combined sensors combine the functions of active and passive.

Principle of operation of the infrared motion sensor

Active devices function in an ultrasound range or high radio frequencies. In the first case, there are limitations up to 20,000 Hz. A person does not hear this sound, but his pets perceive, because of what they behave restlessly. The output is simple - if there are animals in the house, use ultrasonic motion sensors meaningless.

Elements operating in the range of high radio frequencies bypass obstacles - walls and furniture, so they define only the movement of certain objects. With a technically incorrect selection of the connection location, there is a possibility of a false response from the shaking of trees, foliage, moving people in the adjacent room. Add to this high cost.

Based on the foregoing, it becomes clear: to automate the lighting control system in the apartment and a residential building, it is recommended to take passive motion sensors.

Round devices, which is fixed to the ceiling, have a detection zone in all directions - 360 degrees. Elements installed on the walls work under different horizontal and vertical angles - usually 180 and 20 degrees. respectively.

Large viewing sensor

In most cases, the motion sensor is not capable of covering the entire volume of the room, and the detection zone becomes less. Therefore, it is very important to choose the right installation location, the angle of inclination to control the most passable places.

Sensors differ in detection range. At medium devices, this indicator is 12 m. For domestic use, the value is more than sufficient. In the case of a non-standard form of room, the presence of several angles or floors set several sensors.

When considering the design of the instruments, they are divided into movable and fixed. In the first case, the user can make changes to the registration zone by moving the device along the vertical or horizontal axis, and in the second case it is impossible to do this.

Choosing installation site

Timely and correct operation of the movement sensor to switch on the light is associated with the choice of installation location. Follow the following advice:

  1. Regardless of the ceiling or wall mounting, the installation is closer to the door - as soon as the person enters the room, the signal is sent to the controller and the light is instantly turned on.
  2. Avoid installing an item on the central part of the wall, which may be lost sight of the door.
  3. If possible, use sensors in rooms without windows. If it is impossible, then try to remove them to the maximum distance from any sources of daylight. Otherwise, flexible adjustment of the degree of lighting is required.
  4. If in the room more than one door, then installing multiple devices for automatic on / off light. You can set one sensor located in the corner of the room if the detection zone covers both doors.
  5. When using appliances on the landing, they should be fixed above the stairs or to the ceiling, which will allow the device to register the movements from above and below.

Connection schemes

Three contacts are displayed on the motion sensor - "zero", food and outgoing current entering the lighting device. Depending on the number of electrical circuit elements, different connection schemes are used.

Connecting the lamp with a motion sensor is made according to the scheme specified in the attached instruction or on the detector housing.

One sensor

Very simple scheme. One contact is connected directly to the phase, the other is used for grounding, and the third connects the sensor and the lighting instrument controller.

With switch

To the same diagram, a conventional switch is connected to the light that the light does not disconnect or not turned on regardless of the presence or absence of a person indoors, as well as the degree of its illumination. The switch is connected exclusively in parallel.

Lighting circuit with motion sensor and switch

It is important to note that the switch performs only one function - constantly on or off light. One position of the switch disables the detector control (and saves the light in the on or off state), the other - activates it.

Several sensors

Due to the non-standard form of the room, it may be necessary to use several motion sensors. If you install one device into a curved corridor, then it cannot be guaranteed its correct triggering. In such situations, you need to connect two or more devices in parallel depending on the length of the room.

The zero phase is continuously fed to each device, after which the outputs are connected to one wire and connected to the lamp. If at least one sensor has worked, the voltage is fed to the lamp and it turns on.

Important! All motion sensors in the chains must be connected to the same phase to avoid short circuit.

Various interior objects can interfere with the high-quality installation of the electrical element. Choose a place so that the maximum viewing angle is provided, extraneous items did not shield the effect of the device.

Diagram of connecting the lamp to two motion sensor modules

The level of product power is in the range from 500 to 1000 W, which limits their use at high load. If the motion sensor must be powered by several lighting devices, the total power value of which exceeds the recommended, then add a magnetic starter to the chain. LED devices consume a minimum of electrical energy and less demanding of power.

If the lamps contain stranded cables, then use the Special Tips (bushings) of the NSHA.

The order of installation works - step by step

Select where the lamp will be installed and the motion sensor. Install the item by removing the stand and securing on the wall or ceiling. Installation height is not lower than 2.2 m. For 10 mm, clean the ends of the wires connected to the sensor.

Open the detector lid and see the distribution unit with three contacts and multi-colored wires. Blue n - "zero", red-brown (purple) L - phase, yellow or green - grounding.

Connecting the traffic sensor to the searchlight

Connect the voltage to the sensor, in accordance with the colors, connecting with conductive cables of the terminal L and N. Condorate each connection area using couplings, electrical tape. When connected via a double / triple type switch, one of the contacts are used to supply power to the motion sensor.

If the phase feed is confused from the detector to the light bulb, the chain simply will not work. On the other hand, short circuit will not happen - change the wires in some places. The same connection method is used for a circuit with a direct plug connection - the detector functions from the socket like a regular electric device.

At the next stage, the sensor is connected to the lighting device. Phase emerging from the housing, connect to the end of the wire that goes from the lamp. Perform insulation. The other end of the light bulb cable is connected with "zero" on the sensor.

Important! The total power of the luminaires used in the chain should not exceed the specified value from the detector, otherwise the latter fails.

Configure and adjusting the device

The first time is setting up the time during which, from the moment of registration of the last movement (presence) of a person, a voltage is supplied to the lighting device. It ranges from one second to ten minutes.

Existing adjustments of motion sensors

To select the correct time, follow the following prompts:

  • When lighting the stairs, it will take 3-4 minutes, because no one is delayed for a long time;
  • The flow of light in any room should take 10-15 minutes, because the pastime can be short-lived, and long.

To avoid false positives, you need to set the trigger delay after the initial registration of the movement. The parameter also has from one second to ten minutes, and the choice of a specific value is determined depending on the speed of the human movement. Since the corridor moves faster, then the minimum delay is set.

The detector is equipped with a LUX toggle switch, which is responsible for the level of illumination. Here you need to focus on the sensor to work in moments when the room is lighted less. At the minimum or average value, the toggle switch is configured in cases where the device is operated in a room with a large number of windows and other sources of natural light.

Use the Sens toggle switch to configure the sensitivity of the element. The choice of value is associated with the remote from the moving object and its dimensions. If the sensor worked falsely and turned on the light in the room for no reason, then it is necessary to reduce sensitivity. Reverse steps are needed if the sensor did not switch the light at the entrance to the room.

Elimination of possible errors

One of the common errors when installing is bad contact of the zero wire. This may occur when the construction trash in the motion sensor terminal or the weak clamp is made, because of which the nagar or oxidation appears. If the detector does not work, then inspect all the wires, read them and well tighten the clamps.

Another cause of a malfunction is a deformation or breakdown of aluminum vein. Connect to a voltmeter device. Be careful because the device may not work even if there is a voltage. If this happened, then replace the light bulb for a new one, as the problem may be associated with the burnout of the filament.

Another malfunction in the operation of the motion sensor is related to the fact that the lighting device is not turned off, despite the proper operation of the detector. Check what time it was set in the settings. It is possible that it is too large and the output contact for a long time. Reduce the parameter using the appropriate toggle switch.

Only with the correct connection and technically correct adjustment of the motion sensor, you can achieve maximum savings of electricity, comfort and ease of operation of the automatic lighting system. At home, it is recommended to use passive detectors characterized by less cost.

How to connect a motion sensor to a light bulb: Installation location, Connection diagram and configuration

Motion sensor JEX

In order to simplify the lighting management process and automate its inclusion-disconnects of certain places (entrance, corridors, entrance to the house on the street, etc.), such devices are used as motion sensors.

In addition to working in lighting networks, they can be used in security systems. For example, to feed the sound signal (roar of sirens, the inclusion of the call) when the movement is detected in the protected zone.

And they can be configured to automatically open the entrance doors, which is widely used in shopping centers and shops.

Funny doors to the shopping center

Let's consider how to connect this device correctly, we will analyze the popular schemes and list errors that directly affect the error of the device.

Two-Water Motion Sensor Connection

The first to do it, what is your sensor model in connection type. They are two final.

First we study the simplest two-wire circuit.

Two-wire motion sensor in conversion

Two-wire motion sensors are most often put in conventional conversion. The overall picture of its connection consists of 4 elements:

  • Automatic switch for power supply 220V

Connecting the device is similar to the installation of a single-block light switch. That is, you need to supply the supply phase to the sensor, and it is used through it to the lamp.

how to connect a two-block light switch

At the same time, the ligament "Sensor is a lamp", it is better to use on a separate circuit, and not to plant it for general lighting.

Motion Sensor on Common Lighting Apartment

Consider the installation process from the very beginning. The first thing is to start a three-core cable for VVGng-Ls 3 * 1.5mm2 from the machine in the shield in the distribution unit. Denote and label its veins: phase, zero, land.

Cable for motion sensor

Next, stretch the two-core wire to the location of the sensor.

Two-housing cable for motion sensor

Where is it best to post?

A classic version for models installed in the conversion - at an altitude of 1.2-2.0 m from the floor level.

Motion sensor installation height in conversion

Do not confuse with wall devices placed in passing corridors or entrancers, or at the entrance to the building. These usually go to the very ceiling, not far from the door.

Motion sensor on the ceiling

Similarizing that no open doors overlap the corner of the reviewer.

Open door does not overlap the motion sensor overview angle

They are also impresent to put on the battery or other heating devices.

Next, the cable running on the lamp, we also get into the distribution unit. Inseduating all the veins in the next sequence.

Connection of wires in the distribution unit on the motion sensor

Snipalenoli. From the power cable - on the cable of the lamp.

Next Grounding, if it is of course there.

But the phase of the Savtata, connect with one of the residential, go down to the sensor (L). The second germit of the sensor cable, let the luminaire (L of the sensor).

Connection diagram and connecting wires in the camshaft per motion sensor

Because of the sensor itself, the sensor itself is left. The incoming phase with the conditional designation, we bring to the appropriate terminal.

Where the wires are connected on the motion sensor

We connect the second core to the terminal where the lighting device or the load sign is drawn, as in the picture below.

Connecting a two-wire motion sensor

All mechanism and install the decorative framework in the opposition to the opposition.

Installation of a two-wire motion sensor in the apartment

Next on the front panel manufacture setting. To do this, unscrew all the "checkboxes" in order.

  • 1 - Translate the device into automatic mode

  • 2-exhibit sensitivity threshold

In order, the sensor did not turn on during the day or another, the time of day, depending on the level of illumination and the power of the light flux.

  • 3-set time through which the lighting will turn off, as soon as the movement will disappear in the device zone
Motion sensor shutdown time

On this all. We offer tension and check the operation of the whole scheme.

Advantageous two-wire circuit and motion sensor data:

  • Easy installation and connection
  • The ability to enable lighting without additional light switches

You can easily replace any single-block switch with a similar device and automate your lighting system, without any capital costs.

However, there are disadvantages. These instruments are often poorly working with energy-saving and LED bulbs.

Why blink LED bulbs

They begin to meet, sometimes very much.

Three-Watering Motion Sensor Connection Scheme

Go to three-wire sensors with three terminals. The most popular brands in our market are infrared IEK model motion sensors from DD-009 to DD-019.

Motion Sensor IEK DD 009

Popularity is explained primarily by a low price. But also more expensive copies from other manufacturers, in principle, made at exactly the same sample. And the connection process and configuration will be similar.

When buying devices, pay attention to the degree of their moisture protection. In the main mass of IP44.

Outside of the buildings, they can only be put under a canopy or visor. They are not protected from direct rainfall. There will also be fully qualified IP65 models.

Street Lighting Connection Scheme

Also look at the operating temperature if you intend to use it on the street. Most of them are designed to work only up to minus 20s. Next they begin to mercate mercilessly.

The three-wiredatchik will have to start a full-fledged 220V, that is, phase and zero. The whole system consists of 4 elements:

  • circuit breaker
Motion sensor connection circuit with three contacts

At the desires, add another separate light switch. Consider this scheme.

When connecting a three-wire sensor, 3 cables will go to the distribution machine:

  • Three-core from the machine (phase-zero earth)
  • Three-core on lighting (if you have lamps with a metal case)
Connection diagram of a three-wire motion sensor in the distribution

Null to one point. "Earth" from the machine connects to the "Earth" on the lamp. All as the previously reviewed scheme.

Here Tolcon Motion Sensor is already submitted not one phase, but a full phase-zero. A trial device under the case there are three terminals.

Connecting wires on the terminals of the three-wire motion sensor
  • Two introductory - here you start 220V

They can be signed as l (phase) and N (zero).

Three terminals on the motion sensor where to connect wires

The letter "A" indicated for example.

In place to the terminals, unscrew two screws on the housing and remove the lower protective bar.

If Vasuget has three multi-colored wires from the housing, look for the IMMARKING instructions. Usually this:

  • Brown L - phase entrance

But to better wish the cap and check everything visually.

Phase is released, which manages all lighting. In the distribution unit, you have a cable that goes on the lamps or another load.

The whole scheme will look simplified as follows.

Simplified Motion Sensor Connection Circuit With Three Wires
Connection diagram of a three-wire motion sensor

If you do not want to use a dispenser box as a connection site of all wires, then you will have to start all the veins into the sensor itself and connect them to its terminal. Two zero veins twist among themselves and tighten on terminal N.

The phase of the saveate nutrition is allowed to terminal L. Well, and to the remaining output plug-in leaving on the lamp. Roughly speaking, the phase zero from one cable filed, the phase-zero with another brought. Nothing difficult.

Connecting a cable to a motion sensor without camshafts

It turns out the same 3-wired scheme, only without camshafts.

Simple Motion Sensor Connection Scheme

Setting and adjusting sensitivity

After encounter on the case, look for controls and settings. One of the "twist" is responsible during the day. There are painted sun and moon (LUX).

Setting the sensitivity of lighting on the motion sensor

In order to use the device in the bright time of the day, the switch put into the mode where the sun icon. If you need it to work at night or in a darkness, where there is no natural light - unscrew to the moon.

Installation of motion sensor on the street

The second switch sets the shutdown time (TIME). Move the retain from the minimum to the maximum and increase the automatic light shutdown time, from a few seconds to several minutes.

How to exploration so that the device does not accidentally react to domestic animals? Remember the main thing, in this case the sensitivity should be adjusted by non-recorders, and the angle of rotation of the entire sphere.

Motion sensor reacts to a cat and a dog

That is, where the transparent window is watching, it will react to it. You do not want to light up when a cat or a dog runs past, do not send the scope of the down floor. Expose the window perpendicular to the wall plane or at the level of the cheagol.

Well, if you want to want the sensor at all, turn it out at all, then turn it with the "head" so that the window looks at the very top, as if into the sky.

The real zone of the sensor ray capture is approximately 9-10 meters. Although the documentation declares more.

Motion sensor ray capture zone

Tear attention to such a property like sensitivity depending on the human movement. It will be maximal when you pass by, and minimal when you go to meet the rays.

Maximum and minimum motion sensitivity

Therefore, a vhoridore or entrance of high-rise buildings, the sensors are better to put on immediately above the doors, and somewhere closer to the corner. In this case, you will be in any way for any transition, and not to move towards them.

why the motion sensor is better to put in the corner and not on the wall above the door

The main stake of such a 3-wire circuit is the lack of forced inclusion. The motion sensor may fail or start incorrectly. Because of this, you will remain completely without lighting.

To extinguish such problems, use the third scheme with an additional switch.

Motion sensor inclusion circuit with switch

This scheme is the most versatile. It uses a regular classmate.

Motion sensor circuits with switch without it

They differ: "He has only two contacts and two wires, and the sensor has three. How much is it?" Everything is very simple, just connect it in parallel.

That is, the phase from the feeding machine, the need to start not only on the sensor, but also for a single-block light switch. The second wire from a column joins the lighting loop, that is, the quay-water conductor from the sensor.

It looks like a way.

Motion Sensor Connection Scheme with Movement Switch

Now you can include and turn off the lamps at any time, regardless of whether you have or night, there is a movement in the device area or not, it is working or broken.

By the way, if you install the switch is not parallel, and in sequence in the circuit, that is, after it, in order to the phase, you will break up with a completely obvious problem.

Switch successively included to the motion sensor
Motion Sensor Connection Scheme after Switch

It would seem that this option is most good. You can completely disable the entire diagram, and if necessary, turn it on and immediately launch light. But the case is wt that with full de-energization and subsequent supply of voltage, the light bulb does not immediately.

How many beets did not jump before the sensor and did not wave with their hands. He needs a certain time in order to scan the entire area for the presence of objects. Many models are for 10-20 seconds.

And in the meantime, you will stand in the dark and patiently wait for light. Agree that it is not very convenient.

How to connect a three-wire sensor to two wires

And it is possible to limit the 3-wire sensor not in parallel, namely instead of a classmate? That is, throw it out of the scheme and put in the phase break as in the very first service, connecting only two wires and does not supply zero?

With some dedicated light bulbs such a focus can pass. But you need the additional components.

Is it possible to throw away the LED bulbs in the trash
  • Condenser 2,2mkp for 400V

Dijouted between two terminals:

Turning on the diode on the motion sensor
  • N - zero connection

Condensatory is a label parallel. Schematically, it turns out that only the phase will be on the sensor. And comes to contact L, and comes from contact N.

The usual way "A" remains empty. On it "sits" only the scraps and no longer you need to connect here.

Connecting the motion sensor with three wires without zero to two wires

This scheme is useful for those who have only 2-wire cable are laid, and you do not want to change and redo anything. However, it works not with all lamps. Models need to be selected individually.

Connecting the motion sensor through a diode and condenser

Separate uniforms can light, but the ripple coefficient on them will be such a magnitude that it will hit the eyes and vision.

Razzation of LED Light Lights What harm to health is applied as affecting the eyes

Any other load in addition to LED lighting (door opening, alarm, incandescent lamps), it is impossible to include on such a scheme. She simply will not work.

In addition, the total illumination power for such a connection is not more than 80W.

In Tomlush, if you have a very long corridor, and even with turns, you have several sensors along the wall.

To flap a separate power to each of them directly from the switch, use a parallel connection scheme.

Connection diagram with two motion sensors

The number of devices here is not limited. How it works? For example, you visited the beginning of the corridor, the first sensor worked, the lighting caught fire. They came out of his zone, reached the second device - the lighting continues to burn.

Gang height, where the third sensor costs, its elements are closed, the light bulbs are still. And only when you leave the coverage zone of all elements, the light around the gap goes out.

Scheme with starter or contactor

All similar motion sensors are designed to connect the load of the order of 1kW. And what if we are talking about powerful lighting lines performed on dat lamps?


Or even enough so that such devices opened the doors or start the fans? In this loud, use a magnetic starter scheme.

All powerful load will be connected via a starter contacts, and the sensor will control its inclusion coil.

Motion Sensor Connection Scheme via Starter Contactor

The phase conductor coming out of the device is just to power the coil. Zero can allow both directly and from the same sensor.

Motion Sensor Works Incorrect - Connection Errors


False responses.

False processing often occur when exposed to foreign factors. For example, with incorrect location of sensors near the heating elements or inaulice, not far from the trees.

False traffic sensor responses due to tree branches

In the wind, the wreensions of the branches will work and run the lighting every time. Noine, this happens because of the malfunction of the internal components.

To find out what is guilty in false positives, just glue by an opaque tape sensitive window.

because of what the motion sensor is false how to find out

If this does not change anything and the device will still be played out, then he unequivocally failed and it's time to change it.


Connect phase and zero.

From a location of the device's logic, without a difference where you connect the phase, and Kudanol. But from the point of view of security, it must break the phase conductor.

The same thing is valid and when connecting any cartridge of the lamp.

How to connect the floor to the wires to the wire

Therefore, everything is done similarly. Create a phase on exactly the terminal, it is kidnapped by the instructions.


The sensor spontaneously turns on immediately after the disconnection.

This can occur when the outsider beam can be directed, from a nearby lamp in the sensing element.

Because of what movement sensor spontaneously turns on

For example, the nearest incandescent bulb, when disconnected it will fond not instantly, and gradually. And her thread cooling, the infrared waves will still emit.

How to assemble a halogen heater and a simple incandescent light bulb

These waxlovit infrared sensor will work on them, starting the lighting again. And so N-O is the number of times indefinitely.

Threatening that the light from the light bulbs does not beat directly into the sensor itself, or they are from it at a remote distance. Because of this, they are often and hidden directly fodder the luminaire case.

You must unforgettly that there are models ceiling, and there are wall mounted.

Varieties of motion sensors

Both the work of the work is somewhat different. They have different review angle, which means that it will not be planned to work as you originally planned, sometimes at the wrong time.


The effect of wind and glare.

You cannot put the motion sensors aimed at windows, air conditioners or mount them in the street in highly blown places.

Motion Sensor Mounted Near Window

The infrared-receiving receiver located inside, sensitively reacts to any thermal radiation. It means there is a draft or wind, bringing a cold airflow, easily module the intensity of IR radiation in the area of ​​the instrument.

In which places you can not put a motion sensor

It will be carried out from each such impulse, even if there is no movement of Icherovka nearby. And he can work from highlights on a window window or reflected in a puddle.

Some even come across such a rare problem. The sensor is mounted in a plasterboard wall, inside which, for one reason or another, periodically appears the thrust and movement of warm air flow from the bottom up.

So, even the one would seem not obvious thing, this thing can sometimes.


Crack or dirt on the screen.

The fact is that it is not just a transparent glass, as many people think. This is a frenzel lens.

We offer you an exhaustive instruction on connecting lighting devices to different kind of motion sensors or presence detectors. Automatic lighting control is used everywhere, providing not only convenience of use, but also energy savings.

Types of motion sensors

The correctness of the sensor operation depends on the correspondence of its type of operation and installation location. Detection efficiency depends on the type of built-in detector, but it is a completely separate topic. While you only need to determine which differences in the signal conversion scheme, starting from the output of the detector and ending with the contact relay, closing the lighting instrument power supply.

The simplest type of sensors has a built-in contact pair and does not require additional intermediate devices. It is also fair for most of the combined sensors: the built-in comparator compares the signal levels from different detectors and closes the chain only if they all reported on the object detection.


It is more difficult about the sensors designed to work in the complexes Security alarm . This category includes the majority of microprocessor sensors, in the least prone to false responses. At the output, such devices form a digital signal, so the relay is required to install an intermediate module with ADC on board and enhancing the logical level of the transistor.


Typical switching schemes

In general, you can select two types of installation of presence sensors: in close proximity to the lighting device (including together with it in one case), or at a more or less significant distance.

Most sensors with built-in relays have three terminals for connecting. Contacts indicated by L and N are used to connect the supply chain from which the voltage is supplied both on the sensor circuit and on the normally open contact relay. The L OUT terminal, sometimes the arrow marked - this is the second part of the contact pair, closing with the contact L when the sensor is triggered. Thus, the voltage supply is carried out by a two-core cable, the relay contacts are connected to the phase wire break.

Motion Sensor Connection Schemes
Motion Sensor Connection Schemes

If the lighting device costs separately from the sensor, their connection is easier to perform through the junction box. A triple cable comes from the sensor, in which one lived is used as neutral to power the device, and the other two are for switching. The wiring inside the box is performed by the same scheme as for a conventional switch.

Connecting the motion sensor through the junction box
Connecting the motion sensor through the junction box

It is almost impossible to confuse the connection, in the worst case, the sensor simply does not turn on, which is usually observed when the supply phase is applied to the opposite side of the relay contact. Most Motion sensors Not sensitive to polarity, but the phase wire is recommended in the gap - this is the requirement of PUE.

Is there a difference in the type of lighting

As many people are known, the failure of the lamps is not so much due to their long-term operation, as due to spending on / off resource. In contrast to work in a pair with a conventional switch, the ignition of the lamp by the sensor occurs up to 20-30 times more often, due to which the light source fails. If the sensor commutes a conventional incandescent lamp, a halogen spotlight or any other spiral light repairs, it is recommended to set the NTC thermistor in the rupture of the NTC thermistor's power supply chain that proactive currents. Resistance is selected experimentally, depending on the required smoothness of the start, usually within 200-1500 ohms.

Connecting the motion sensor to the light bulb through the thermistor
Connecting the motion sensor to the light bulb through the thermistor

Energy saving and fluorescent lamps are less sensitive to frequent inclusion, but only if there is a hot start in their power supply. The delay in the inclusion of such lamps can negatively affect the convenience of use. You should increase the sensitivity of the sensor and selectively select its type.

On LED devices, the inclusion frequency does not affect almost no effect. It is recommended to switch the sensor to the power voltage to the power supply. This will not only eliminate the parasitic consumption at idle, but will also eliminate the rattles of contacts at the expense of the food built into the power supply.

Control of increased load

Almost all sensors, judging by the label, are designed to switch the load at 10 or 16 A, and the practice shows that even these indicators are greatly overestimated. If the power of the light instrument is more than 1 kW (current 4.5-5 A), it is recommended to add an intermediate switching device to the circuit.

If the lamp connection to the sensor is made through the junction box, the task will solve the compact magnetic contactor. Devices for mounting on DIN Rake are sufficiently small for fastening them to the side wall of the box. It is important to monitor that the supply voltage of the contactor coil was equal to the network. In this case, the coil replaces the lamp in the standard diagram, and the lighting device itself is connected through the main runner terminals.

Connecting the motion sensor circuit to lighting through the contactor
Connecting the motion sensor circuit to lighting through the contactor

In some cases, even compact Modular contactor May be inappropriate. Here you can resort to the method of contactless switching by high-voltage field transistors. The scheme bribes simplicity, besides, it can be collected even by mounted installation. For example, we take IRF740APBF - a powerful N-channel transistor with a maximum operating voltage 400 V and a load current to 10 A. To build a circuit, a pair of such elements will be required: we are dealing with alternating current, respectively, the half-wave need to be skipped in both directions.

The power part of the scheme consists of two identical transistors, their drain and source connect is connected and installed in the rupture of the load power chain. The control part of the scheme does not have a galvanic junction, it consists of a protective straightening diode with a breakdown voltage of at least 300 V, as well as a voltage divider of two resistors included in series. The recommended IRF740APBF opening voltage is 25 V, that is, about a tenth of the network - the ratios shoulder values ​​should be distinguished at the same time. You can confidently take resistors at 47 and 4.7 kΩ, connecting the shutter through the midpoint. The scheme can be supplemented with a shunt resistor with a nominal value from 100 kΩ connected between the shutter and zero wire through the diode. The shunt is needed to suspend the low level of the control signal in the off state, for such powerful bevels with such a container it can be very critical.

Setting up operation modes

Most standard sensors have three regulators on their housing: Sens, Time and LUX. Before switching to their setup, you need to make sure that the sensor itself is installed in the correct position and the angles of its view completely overlap the pass control zone. To do this, you need to install the SENS knob to the limit position, and then check whether the detector works at a person input to the controlled zone. The Sens regulator can correct the range of the sensor, for example, to work on people suitable for the entrance, but not by passing cars.

Photo IEK.ruMicRolve Move Sensor DD-MV 201

Using the LUX controller is determined, with what light level it is necessary to include additional light. It is recommended to adjust this setting during twilight, installing the venier to the position on which the sensor is just starting to work. Finally, the Time regulator determines the duration of the light on, this parameter is configured individually.

Connecting multiple sensors

Premises and control zones may have a different form and size, while the sensor controls only one lighting or network. To ensure confident detection of presence, the sensors can be placed at a certain angle to each other, meet and multidirectionally, providing the maximum coating zone by detectors.

Usually it is necessary to turn on the light when at least one sensor from the group is triggered. In this case, the contacts of relay groups of all detectors are connected in parallel. It is only important to monitor that all group sensors are switched to either phase or zero wire, otherwise a short circuit will occur with a high probability when switching on.

Parallel Motion Sensor Connection
Parallel Motion Sensor Connection

If the light should be turned on only when both sensors are triggered at the same time, the task is complicated. If one contact of the relay was not associated with the power supply, the sensors could be connected by contact groups sequentially. Because of this feature, the installation of an intermediate relay is required, the coil of which is turned on when one sensor is triggered. In this case, the load is first bursting with the contacts of the second sensor, and then the normally open contact of the additional relay.

Motion Sensor Connection Scheme for Lighting to Projector or Light Bulb

Elimination of false positives

Summing up, we will give an important recommendation on how to eliminate false positives. Sometimes the sensitivity adjustment does not give the desired result: the sensor either continues to work in a frightened one, or ceases to react in general due to the narrowing of the control zone.

Typically, such behavior is characteristic of microwave sensors for which no window with doors or even capital walls are not an obstacle. Thus, the sensor installed in the apartment can work on movement in the entrance or at the neighbors. The first thing to be done is to make sure the sensor orientation of the sensor and, if necessary, change its direction and installation location.


If it is impossible to make it impossible, several sensors should be installed with the calculation of their joint response. In this case, the sensitivity sensors are selected close to the minimum, usually such a solution is well suited for small rooms and tambours, as well as when implementing complex schemes Lighting control .

Man is a reasonable creature, loving comfort in everything. Therefore, if it is possible to create it, then he does not miss such a chance. And even in the case when to achieve a goal is to work well enough. Recently, the "smart home" superpopular systems are becoming superpopular systems, which are mandatory included devices that control lighting. To automate the inclusion and shutdown of lamps located in the entrances, apartments, before entering the house or in the corridor, the motion sensors are now used. The same devices become an integral part of the security systems, are used in stores for "consumer convenience" - to open doors in front of buyers. These devices promise "two in one" - the maximum comfort and savings of electricity, so many would like to know how to connect the motion sensor to the light bulb. As with all work, this operation has features, schemes and requirements.

Motion sensor: principle of operation

Motion sensor, or DD - almost an integral part of the Smart Home system, but it can be used separately. This is a device reacting to the presence of a person (or animal). The main task of this detector, like any other, is the control of the electrical network. It can work with an active or active inductive load.

How to connect a motion sensor to a light bulb: Schemes, Connection, Setup and Installation

When in the control zone of the instrument having a photocell, movement is detected, the device first checks the level of illumination. If this parameter is below the specified value, the sensor turns on the lighting device. Motion sensor threshold The owners are set by the regulator: its range is 3-2000 LCs (10-2000 LC).

Sensors IR, more often used in living conditions, capture the oscillations of electromagnetic waves in the infrared spectrum. The time, through which the triggering, like its threshold, is also configured independently by the owners. Exposure of the device depends on the model. It can be from 10 seconds to 15 minutes. A small error is allowed.

Installation Plant Requirements

Before studying the question of how to connect a motion sensor to a light bulb, you need to solve the other: how to find the optimal place for the device. From this, as from the correctly selected connection scheme, the sensor operation depends in the future. Much depends on the device gripping angle, but any sensor must be set so that its action zone covers a greater number of people's appearance places.

Montaja rules

How to connect a motion sensor to a light bulb: Schemes, Connection, Setup and Installation

With one entrance to the room, the sensor is installed opposite it. If the doors leading to the room are two, then the optimal placement of the device on the ceiling, but only the device with a maximum coverage angle is suitable for this installation - 360 °. But this is not all, because there are several more rules.

  1. Owners need to be traced that there are no devices using electromagnetic radiation in the working area of ​​the sensor. Otherwise, interference is inevitable.
  2. Near the device should not be installed, fans, climate control systems. Heating radiators, other heat sources are also not the best neighbors for the detector.
  3. We absolutely do not allow direct sunlight falling to the device. If there is a window, it is important to adjust the device so that it turns on the light only in the dark.
  4. Incandescent lamps in the detector action zone are not recommended, since the sensor can react to a change in its temperature.
  5. At the radius of the motion sensor should not fall any major objects (for example, massive furniture), which can prevent the review.

Sensor installation height - 2.5-4 m. This parameter may differ slightly at different models. Sensors, detecting presence, are more sensitive to movement across the observation zone, as well as to vibrations.

Other mandatory conditions

How to connect a motion sensor to a light bulb: Schemes, Connection, Setup and Installation

There are limitations regarding the total capacity of lighting devices. For conventional incandescent lamps, the limit is 1200 W, for luminescent - 600 W. The temperature also affects the sensitivity of the detectors. The optimal mode is the usual "room indicator", which is more often not exceeding 20 °, but the devices can operate at temperatures from -20 ° to 40 °. Compliance with these recommendations will avoid two opposite problems - false response and, on the contrary, unformation.

For apartments and houses in which pets live pets, there are two options for solving a "wandering object". Their owners can adjust the sensitivity of the sensor (or the position of the lens), prudently setting the minimum value for the trigger. The second option is to buy a detector, "default" that does not respond to the movement of "fearless", weighing less than 10-25 kg.

How to choose an optimal sensor?

Before considering the question of, connecting the motion sensor to the light bulb, you must purchase it. And this is sometimes the main problem. Equipment of the sensors of an apartment or houses, utility rooms or yard is a task that seems simple only at first glance. The range of such devices is quite wide, all of them have advantages, disadvantages, their own features and different installation methods. Therefore, the future owners have to solve several issues at once.

Place placement

How to connect a motion sensor to a light bulb: Schemes, Connection, Setup and Installation

Internal devices are used to work in buildings, which are designed to work under normal conditions - without temperature differences, high humidity and dust. For installation outside the room, the device must have protection against exposure to external factors. As a rule, such "malicious" detectors need a larger detection radius.

Device type, additional features

After determining the place of installation, the type of motion detector is chosen. Infrared devices belong to universal products. They can function both in the rooms and out of them. Acoustic models are the optimal choice for sections, where the rare appearance of visitors accompany the sounds - cotton, knock door.

Long corridors, placing a complex configuration - a reason for buying ultrasound or microwave sensors. Combined devices combine the properties of several types of devices. Their advantages are reliability, the minimum number of false positives. It is believed that the most unwanted option is ultrasound sensors. At least for families in which pets live with sensitive ears.

How to connect a motion sensor to a light bulb: Schemes, Connection, Setup and Installation

It is better to learn in advance about additional features. One of them was mentioned. If the house "gracious" (travels at night) animals, then protection against false positives is required. When the device has a movable element, it is recommended to direct "on the shoulders" of people. It is said that in this case "wandering" of pets remain unnoticed.

The disconnection delay is necessary to relatively large rooms, otherwise the owners threaten "Walk in the dark". The built-in illumination sensor will not allow the lamps to turn on, if the room is not dark enough.

Connection options

The choice of method depends on what exactly needs home or apartment owners. There are three possible connection scripts.

  1. Independent inclusion: or sensor, or switch. In this case, the owners will have the opportunity to use the sensor and do without it, when there is a need for this.
  2. Sensor that can be turned off for a certain period. It can be convenient if the light is often turned on by residents in the bright time of the day.

How to connect a motion sensor to a light bulb: Schemes, Connection, Setup and Installation

Universal solution - a combination of methods. This is an automatic associated mode with the forced switching / off light. This option combines both previous ones. In addition, it is possible to connect detectors in parallel. This solution is optimal for long corridors in which several doors come out.

Viewing angle, range

Viewing angles determines the number of inputs into the room or paths to the object. Than they are smaller, the smaller the angle is required to the instrument. For premises with several doors, for open spaces, the optimal models that have horizontal angles horizontally 180-360 ° are optimal. If there is only one entrance door in the room, the narrow sector (110-180 °) coverage is quite enough.

Vertical viewing angles are significantly less than 15-20 °. The range of the device also depends on the scale of the area under the control. For the installation of internal models, their "strong limblessness" - the requirement is clearly unnecessary. For rooms there will be enough detector that can recognize movement from a distance of 7 meters.

Protection against adverse conditions

First of all, we are talking about wet rooms and street. For rooms with normal humidity, you can purchase devices with IP20 protection class. Devices that will be mounted on the porch, gazebo, terrace, need a higher level - IP 33.

Detectors designed to work in bathrooms and bathrooms are required to have an IP security class 44. The same, the most secure devices are installed in the open area, but additionally they are advised to protect the visor.

Method of installation

Sensor models are case, which is chosen for mounting on walls or ceiling, and embedded. Recent devices have small sizes, but differ in high price. For these reasons, these motion detectors have their own "niche": they are purchased to organize security systems.

Determination of the load

One sensor can be connected to several instruments, so in this case it is important to comply with the prerequisite: their total power should not be higher than the limit specified by the device manufacturer. To a greater extent, it concerns street lighting systems, which includes more powerful light sources.

How to connect the motion sensor to the light bulb?

The answer to this question depends on the variety of sensors, from the installation site, from the connection scheme. Before connecting the motion sensor to the light bulb, you need to decide exactly how it is better to do. There are several options, but first it is recommended to turn off the electricity, and the device itself is disassembled. The rear panel of the sensor is removed using a screwdriver. It is detected by a block for connecting wires.

How to connect a motion sensor to a light bulb: Schemes, Connection, Setup and Installation

All contacts inside the device are designated: n - neutral (zero), L - phase, and l with an arrow (or a) - a terminal designed to connect to the lighting device. Connection diagram of a specific sensor manufacturer is also provided. It is either on its housing, on the back side, or is present in the instructions. Therefore, the owners remain only to follow it, or choose the best way to connect. Different connection schemes, the inclusion of additional devices will allow you to expand functionality, increase the area of ​​the controlled zone, to be able to manage the group without the participation of the sensor if this condition is necessary.

Schemes: three-wire and two-wire

All inexpensive sensors intended for installation in apartments and private homes can be divided into 2 types - two- and three-wires. The first scheme is similar to that which the standard switch is connected.

How to connect a motion sensor to a light bulb: Schemes, Connection, Setup and Installation

The second implies the presence of the zero wire. The lack of both options is the impossibility of adding an additional device that will enable or turn off the light forcibly.

How to connect a motion sensor to a light bulb: Schemes, Connection, Setup and Installation

Connecting the sensor bypassing the switch

This is the easiest answer to the question, how to connect the motion sensor to the light bulb, since no other devices are provided here. In this case, if a moving object appears in the detector zone, it will work - independently turns on the lighting device. Plus the method is easy operation, since additional manipulations are not needed with a junction box.

This option is the best solution for those places where the owners do not remain for a long time. For example, for the porch, the staircase, pantry, etc. The motion sensor will include the light that will burn until the zone moves. Some time after the care of people, he will turn off. The method is convenient because no additional actions are required of the owners, and this is important if there are hands.

How to connect a motion sensor to a light bulb: Schemes, Connection, Setup and Installation

Connect the device directly very simple. From the terminal L lead the wire to the phase, from n - to the neutral of the lighting device, and from l with the arrow (A) - to the light bulb phase. If work leads at the local area, then, as a rule, several detectors are installed - two or more. Their terminals are connected in parallel, and then sum up to the lighting device.

Connecting the motion detector via switch

This option is a bit more complicated, but in some cases it is considered to be the optimal choice. For example, such a scheme becomes the only possible choice for kitchens. When the hosts come to the room, the lighting device turns on, however, after the owners sat down at the table, and stopped moving, the detector simply turns off the light. Conveniently, it is difficult to call such a work of instruments, so the position saves only the presence in the chain of the three-position switch. In addition to the kitchens, this scheme is used for bathrooms, bathrooms and toilets.

How to connect a motion sensor to a light bulb: Schemes, Connection, Setup and Installation

In this case, they act in this way:

  1. First, from the terminal N zero conductor is carried out in the junction box. There are laying on the light bulb.
  2. From L phase fudge to the switch, where it is connected to the middle terminal, which is assigned to the "independent" work of the detector.
  3. The terminal A of the sensor is connected from the phase of the lighting device. Then connect the light bulb and switch: the wire is summarized to the terminal corresponding to the top position of the key.

The presence of the switch will allow you to independently include lighting. The lower position of the key will provide its shutdown without the help of the motion detector.

Fixing the sensor and its setup

After the installation is completed by the selected scheme, the body of the instrument is collected, then it is fixed on the ceiling or wall. For this, the holes are drilled at the base, the dowels are inserted into them, then the device is screwed with self-draws. With a rotary case, the device unfold so that it covers the action zone as much as possible.

How to connect a motion sensor to a light bulb: Schemes, Connection, Setup and Installation

Then go to the setting of the motion detector. Standard models provide for only 2 regulators: the (Time) of the luminescence of the lamp and sensitivity (SENS) of the sensor is triggered. More functional models equipped with a photocell (photoele) allow you to adjust the light level (LUX), at which the detector will turn on the lamps. Combined devices can have built-in microphones. In such models there is a regulator of their sensitivity (MIC).

However, even two regulators make it possible to configure devices without any problems for any working conditions. There is no big difference in adjusting detectors of different types (and manufacturers). In any case, the operation is carried out when the light is turned off.

  1. The sensitivity controller turn clockwise until it stops. The time regulator, on the contrary, is counterclockwise, too, to the limit.
  2. After a few minutes they go to check. The room leave, then returned to it. Ideally, the time period between tests should be more than 5-10 seconds.
  3. After testing, configure the response time and sensitivity of the motion sensor. The duration of the glow is selected by the hosts: the range is wide - from 10 seconds to 4 minutes. As a rule, this operation takes some time necessary to check the selected mode and its subsequent adjustment.

How to connect a motion sensor to a light bulb: Schemes, Connection, Setup and Installation

Instructions instructions include a detailed manual that helps relatively quickly and correctly adjust the devices. Therefore, any owners will cope with the task: both connections, installation and detectors settings.

Possible problems

Unfortunately, not all and not everyone goes smoothly. Sometimes the hosts face problems due to incorrectly performed work, not quite correct installation, etc.

How to connect a motion sensor to a light bulb: Schemes, Connection, Setup and Installation

  1. False responses. They are possible in several cases. As a rule, such troubles are caused by the improper location of the instruments that are forced to react to heat sources, on the foliage of trees or other random factors.
  2. Reacting - the inclusion of lamps is without any reasons. The reason can serve as the light of another source, if it is directed to the photoorele, the incandescent lamp that cools not immediately. In addition, sensors can "catch" IR waves.
  3. Air flow. Infrared sensors are capable of catching not only glare, but also air flows, so they are not recommended to install in places of potential drafts, in those open sections of the local area, where the strong wind is rather a rule than an exception.
  4. The emergence of problems due to improper installation. In this case, we are talking about the installation of the sensor intended for installation on the ceiling, on the wall, or vice versa. The reason is a different viewing angle of such devices, so incorrect work is the consequence that you can expect if the owners ignored the manufacturer's instructions.

How to connect a motion sensor to a light bulb so that when operating it, do not encounter problems? In this case, you need to correctly select the controlling device and the scheme, comply with all the requirements for the place, connecting to the network and installation. To know what scenario is such work, it is better to watch "visual video":

The joint work of the motion sensor and the lamp increases the level of comfort in the house, apartment and even the office. The lighting is included independently at the time of fixing a person who has entered the room. When the room is empty, the light automatically goes out, and this is an additional electricity savings. To connect the motion sensor to the light bulb, the article presents the installation schemes, the basic rules of connection and the principle of operation that even beginner electricians can disassemble.

The main functions and principle of work

The motion sensor is designed to detect the moving object and feed the corresponding signal to the control body through the switching of the electrical circuit. Works with active and with an active inductive load in the chain.

If a movement is noticed in the controlled zone, the chain of the illumination process is started (if the sensor supports this function). When reading below the setting threshold, the contacts are closed, the current is fed to the lamp and the lamp lights up.

On this principle, the sensor is ready to work in a dark and bright day of day. The trigger threshold is set by regulators in the range of 3-2000 LCs.

But the motion sensor can work on another principle: capturing the electromagnetic fluctuations of the waves in the infrared spectrum. At the same time, sensors often have an adjustable delay on switching on when motion is detected.

Exposure mode is set using the rotation of the regulator. At the same time, the delay for triggering can be different: from 10 seconds to 15 minutes.

Connecting the motion sensor to the light bulb

At the same time buy a finished product in the form of a lamp with a sensor is not necessary. It is enough to purchase a suitable sensor on this role and turn it on in the circuit circuit.

Two-Water Motion Sensor Connection

Not depending on the design, the motion sensors by the method of connection are divided into two-wire and three-wires.

According to the design, two-wires are usually placed in conversion. The main elements for connecting:

  1. Automatic electrical appliance switch from the 220V network (usually located in the distribution shield).
  2. Distribution box (usually drilled in the wall / ceiling).
  3. Motion Sensor.
  4. Lamp.

Connecting the sensor is exactly as a single-block switch for artificial lighting. That is, the phase for which the current will be passed, must be tested to the sensor, and it is used to put further on the lamp. It is recommended to make installation on a separate circuit, and installed on general lighting.

Connecting the motion sensor to the light bulb


The installation process is happening like this:

  1. Start the three-core VVGng-LS 3 * 1.5 mm2 cable with an automatic shield switch to the distribution box. Marck the veins for convenience: l (phase), n (working zero), zero protective or earth (PE). Connecting the motion sensor to the light bulb
  2. Two-core wire (extension) are moving on the other side to the distribution unit, connecting the pre-sensor from the other side through the clermets. Connecting the motion sensor to the light bulb
  3. It is recommended to place a motion sensor (if it is a conversion) at a level of 1.2 - 2 meters from the floor level. Connecting the motion sensor to the light bulb
  4. Such sensors should not be confused with the walls, which are placed at the entrance, in the corridors or in the entrances of a multi-storey building. Those that are used for lighting are usually installed under the ceiling near the doors. Connecting the motion sensor to the light bulb
  5. The level of the review should not be overlapped by moving objects (open doors or curtains). Connecting the motion sensor to the light bulb
  6. The cable from the lamp also get into the distribution box. Connect the sperm of the nutrition of the power + lamp. Then grounding the first and second cable together. Connecting the motion sensor to the light bulb
  7. Phase (L) from the circuit breaker, connect with the first residential. Connect the second residential to the phase (L) of the lamp. For high-quality and aesthetic connections, it is recommended to use the WAGO terminals.
  8. The connection of the sensor in the submersion is proceeded according to the scheme: the first lived (which goes from the machine) connects to the socket with the designation (L).
  9. The second core starts in the nest with the labeling "load".
  10. The connected sensor hide in the opposite and wear the body of the structure.


Electrical connection completed. Now on the front panel, configure the sensor:

  1. Scroll through the first knob to install auto mode.
  2. The second controller is responsible for the sensitivity to the light. To activate the sensor only in the dark, turn the regulator to the desired number of degrees left.
  3. Timer turning off the lighting in the absence of movement in the controlled zone. The time range is usually indicated by the characteristics of the device, in the instruction manual.

Ready. In the camshaft, translate the circuit breaker to the "enabled" position and check the work just performed.


Among the positive moments of this scheme can be allocated:

  • Simple installation and step-by-step setting;
  • Versatility;
  • Automatic switching on light without installing additional switches;
  • Interchangeability with a classroom switch.


The substantial minus of the two-wire sensor is poor interaction with LED and energy-saving lamps. The latter can greatly flicker that in addition to discomfort increases the possibility of rapid burnout.

Three-Watering Motion Sensor Connection Scheme

Sensors with three terminals are commonly used when constructing an IR sensor. A rather common manufacturer of inexpensive infrared motion sensors is IEK. Without special problems, you can find good products for Aliexpress.

Three-Watering Motion Sensor Connection Scheme

Products are more expensive by a similar principle, the diagram of connecting the lamp with the sensor is similar to the sensor model from any manufacturer. Devices should have the degree of protection of IP44 from the penetration of solid objects more than 1 mm and drops of moisture. If the sensor movement needs to be taken out of the house, the installation is possible only under the visor.

If you want to protect the device from rain and snow, look for an IP65 dust-hearted model and with a temperature regime for your climate. Most IR sensors can only work up to minus 20 degrees Celsius.

To connect a three-wire IR motion sensor, a full phase and zero starts. For the correct placement, you will need all the same basic 4 elements:

  1. Automatic switch (in the camshaft).
  2. Distribution (in which the main installation).
  3. Sensor (a wire from the distribution unit is connected to it).
  4. Lamp (second wire from the distribution-cutting).

Sensor connection with three wires will be carried out with a plant in the distribution box of three cables:

  1. From the machine three veins: L (phase), N (working zero), zero protective or earth (PE).
  2. There are three veins on the lamp if the housing of the lighting device is made of metal.
  3. Three veins per sensor.

How to connect a motion sensor to a light bulb using three lived, considered in detail in the diagram.

How to connect the motion sensor to the light bulb

Zeros (N) are collected at one point (as in the case of the previous scheme). Earth from the circuit breaker also connects to the land of the lamp (zero-drive or PE). Phase-zero is now served on the motion sensor with three terminals:

  • Two introductory - for powering 220V, usually signed as l (phase) and N (zero). How to connect the motion sensor to the light bulb
  • One conclusion is denoted by Literura A. How to connect the motion sensor to the light bulb


To install a three-core motion sensor:

  1. Unscrew two screws in the housing. Terminals are under the rear lid. Installation of a three-core motion sensor
  2. Some models are already outlined from the body with three wires of different color. In color, it can be determined that it means: the earth (a) is red, zero (n) blue, phase (L) brown. But if the lid opens without special dyg, it is recommended to make sure that there is a certain marking personally, looking at the inscription next to the terminals. Installation of a three-core motion sensor
  3. A simplified scheme for connecting the motion sensor to the light bulb looks like this: Motion Sensor Connection Scheme
  4. A little clarity here is in this picture. Motion Sensor Connection Scheme
  5. You can do without camshafts for connecting wires and all the veins will start directly into the sensor box, if inside is quite spacious and there is own terminal bar. The phase zero from one cable filed, and from the other phase-zero derived.
  6. It turns out simplified, but the same three-wire scheme, only without a distribution box.

Setting and adjusting sensitivity

After successfully connecting the lamp with a motion sensor, it is necessary to correctly set its parameters:

  1. On the back of the housing, find the main regulators. LUX with the positions of the month and the Sun is responsible for triggering depending on the illumination. It is necessary that the sensor is turned on in the room with the window only when will it be overcast or will the sun go? Unscrew the regulator towards the moon.
  2. The second regulator exhibit shutdown time. The delay can be set up from a few seconds to 5-10 minutes.
  3. The angle of rotation of the entire sphere allows you to adjust the detection of animals.

Benefits and Nuances of Use

So that the sensor does not react on the animals, do not rotate the sensor head down to the floor. Stop it so that he captures movements at the head level (shoulders) of all residents of the house. Usually, at this level, animal capture does not occur.

If it is necessary that the sensor is temporarily not triggered, then the head direct it into the ceiling. Thus, the capture of displacement is impossible. The capture of motion by the sensor depends on the angle of inclination. In the realities, the maximum distance reaches 9 meters. But on the passport may be higher.

Capture motion sensor

Sensor for detection applies IR rays. If you move from the beam to the beam, the device notices activity and reacts. When you go straight to the beam, the sensitivity of the sensor is minimal and the device may not immediately react to you.

For this reason, the installation of motion sensors is carried out not directly above the doorway, but a little side. For example, in the corner of the room.


The disadvantage of the three-wire circuit of connecting the motion sensor to the lamp is the lack of inclusion of the light forcibly. If the sensor is for some reasons to come into a malfunction, problems will begin with its correct operation. To avoid this, it is recommended to add a switch into the circuit.

Motion sensor inclusion circuit with switch

This scheme is considered universal, because a single block switch is applicable in it.

Motion sensor inclusion circuit with switch

Since the switch has two wires, and the sensor has three, there is a wonderful method for this - parallel connection:

  • Phase from automatic power Caeden simultaneously on the switch and sensor (WAGO terminals to help).
  • The second wire from the switch with one key, attach to the output conductor from the sensor (again using the WAGO terminals).

This scheme will allow you to turn on and off lighting in the room, regardless of the operation of the motion sensor. Even if it breaks temporarily, you will not stay without lighting at the right hour.

Serial connection (the phase break occurs to the sensor) in this scheme has a significant flaw - complete de-energization of the motion sensor reces its initial settings to which it returns for 20 seconds. Imagine the situation that you turned on the light, stand in the dark, make hands before the sensor, and he does not respond to these movements. Comfort from such a gadget will volatile instantly.

Connecting a three-wire sensor to two wires

Quite a fairly frequent question: Is it possible to connect a three-wire sensor in parallel with the switch, and instead of a single block switch. In fact, remove from the diagram and allow the phase into rupture, as in the case of a two-wire circuit.

Theoretically, it is possible and with some luminaires this focus really will work. But this will require additional:

  • Diode VDI 1N4007;
  • Condenser 2.2 μF per 400V.

The diode must be installed between the two terminals A-outlet from the sensor and where zero N is connected. The condenser itself is necessary to solder in parallel with the light bulb in the lamp. According to the scheme, it turns out that one phase comes to the sensor, it comes to contact L and leaves from contact N. The output and the view remains not connected.

Connecting a three-wire sensor to two wires

The scheme is popular with residents of houses, where the two-housing power cable is laid and you do not want to change something in this direction.


Minuses are as follows:

  1. Does not work with everyone in a row LED lamps.
  2. Pulsation can be so high that it will cause sufficient discomfort by creating an extra eye load.
  3. Add any other load in the diagram cannot be, because nothing more will earn nothing.
  4. The maximum power of this lighting is 80W.

Scheme with two sensors

If you need to illuminate a long, M-shaped or other view, you will need to set several sensors to capture the movement. In order not to use extra cable meters, connect both devices over a parallel scheme.

Scheme with two sensors

In this scheme, the number of connected sensors is not limited.

It works for this principle:

  • Stopped on the threshold of a long corridor with an angular turn and the light automatically caught fire.
  • They reached the activation zone of the second sensor - the lighting did not stop.
  • Rotated 90 degrees and your movement caught the third sensor. Lighting continues.
  • Leaving the corridor completely, the lighting stops.

Scheme with starter or contactor

Previous schemes for connecting the swims for the load within one kilowatta. But there is an alternative type of lighting with powerful loads, such as arc sodium tubular lamps. Or a large load is necessary to start the fans in the hood along with the lighting.

In this case, a starter circuit is applied (the load runs through the contacts of the starter). And sensor-IR in this scheme controls the contactor coil.

Scheme with starter or contactor

The output contact from the sensor under the voltage will powder the coil. Zeros are combined into one common.

Problem problems or connection errors

As problems with the operation of motion sensors, it is allocated:

  1. Connect phase and zero. According to the logic of the device, it is still where zero and phase will be connected. But for security reasons, the rupture should be located on the conductor subordinated to the phase. An analogy of such an inclusion can be brought with a lamp cartridge.
  2. False responses. It is possible with the improper location of the sensors, the installation near warm or heating elements, installation on the street, not far from the leaves of the tree or other foreign factors.
  3. Rightly inclusion immediately after deactivation. If a lamp or another radiating light is directed on the sensor photorele, this will serve as a device behavior. Not far placed lamp with incandescent lamp, which does not fall off at once. The sensor can catch IR waves and run the lighting chain. Cases of an infinite activation cycle on IR-Waves are not excluded.
  4. Installation of the motion sensor on the wall, although on the passport it is ceiling. Not enough in the specifications of the mounting option (wall / ceiling) is specified. This is due to the device diagrams. Such devices have a different viewing angle and as a result, problems occur during incorrect installation.
  5. Glare and air flows. Factors such as glare and strong air flows force to react an IR sensor. If there is a similar situation with highlights of a similar situation in the third point, then with the wind of things are different. Installation is not recommended with a direction on the windows, split-systems, on the street where strong drafts are walking.
  6. Cracks or the appearance of contamination on a sensitive element when connected to the searchlight. These elements in the sensor serves as an Fleel lens. It is needed for focusing IR radiation with the help of within concave segment mirrors. If the contamination has a lot or in front, the crack will appear, it means that the device works incorrectly.


The article considers the question of how to connect the motion sensor to the light bulb using various schemes. Simple and universal is the connection of the sensor with two terminals. But in order to achieve trouble-free lighting with the use of LED and energy-saving light bulbs, it is recommended to use sensors with three terminals and connect along a three-wire connection diagram.

If a three-wire circuit is supplemented with a single-button switch parallel connection, it is possible, regardless of the operation of the sensor, turn on and off the artificial light in the room manually.

The use of the motion sensor to activate the light at the time of approaching the lamp significantly increases the level of comfort in the home / office / apartment. The miniature instrument is heading for you by the system, allowing you to take care of such trifles. Reduced electricity consumption, and you can easily install it with your own hands.

Economical on all sides by the device should be taken. Agree? We will tell you how to connect the motion sensor to the light bulb. In the article submitted, the article presents technological rules and schemes available to the beginning of the electrician. Listed options are listed, the specificity of the setting is described.

Motion Sensor: Basic Functions and Operation Principle

The main purpose of the motion sensor is the switching of an electrical network. It can work both with an active load in the chain and with active inductive. Any movement in the control area primarily launches the process of determining the level of illumination (if such a function is provided in the device).

If the indicator below the set trigger threshold, the device closes the contacts and turns on the lamp. Thus, the detector can work both in the night, and during the daytime. Install the trigger threshold using regulators, it can be from 3 to 2,000 LCs.

In everyday life, the devices of which are based on the capture of electromagnetic wave oscillations in the infrared spectrum. The time through which the detector works, in the event of a detection of a moving object, is also configured.

Turning the regulator, the shutter speed is set. At different models, the delay time can be adjusted from 10 seconds to 7-15 minutes (a small error is allowed).

Principle of operation of the motion sensor

The work of detector devices is based on the detection of motion or at identifying a person's stay in the review zone

Literators of competent selection

Different models can have a different purpose. Some are intended only for controlling inner lighting devices, others are more universal and can be used for electrical appliances schemes with alarm devices, s.

Sensors can be with a limited and circular overview, have different angles of horizontal and vertical observation. Devices for connecting the wall control the zone at an angle of 110-120 ° or 180 ° horizontally and 15-20 ° vertically.

Models with a moving organ of review significantly facilitate the setting, but stationary do not have such an opportunity, so they need to carefully choose the placement location.

Sensor overview angle

In models with a limited overview, the viewing angle may vary and make up from several units to hundreds of degrees. When choosing a device, you must consider what area will be able to control the device

Circular overview detectors can cover a controlled zone at an angle of 360 ° horizontally. Their viewing area has a cone form that expanding the book. Despite the large control zone, not viewed sites (outside the radius, in the corners) in the room still remain.

To install the sensor on the street or in rooms with high humidity it is necessary to choose a device with high on external factors (dust, moisture).

For example, devices with a protective degree of IP20 are permissible to use only in interior with normal humidity, with IP33 it is possible to install on the street - on the terrace, porch, gazebo. With IP44, you can mount on the street, but to protect the visor from the drops of water droplets during atmospheric precipitation.

You can buy a ready-made complex from. With the peculiarities of its choice and the installation will introduce the article recommended by us.

Placement and method of orientation

General rules for setting sensors are as follows:

  • The height of the installation above the observed surface can be from 2.5 to 4 m (the parameter depends on the device model);
  • When choosing a place for installation, take into account the fact that the detector is more sensitive to the movement, which occurs across the observation area;
  • The total load capacity of the lamps is limited and can be, for example, from 60 to 1200 W for incandescent bulbs and from 0 to 600 W for fluorescent illuminators.

The sensitivity of the detector also affects the temperature and temperature. The range of temperature values ​​in which the device normally performs its functions - from -20 to 40 ° C.

Sensor installation

Ways to install traffic sensors using the example of TDM Elektrik devices: DDPT-01 mounted in the cartridge; E27, DDT-03, DDT-02, DDT-01 are installed in the mounting hole for point luminaires (the diameter of different devices is different and can be 40-65 mm); DDSK-01 can be mounted in the wall, ceiling, luminaire case

It is forbidden to install lamps:

  • on vibrating surfaces;
  • near fans, air conditioners;
  • on glossy white surfaces of the walls;
  • near heat sources -, lamps;
  • On the surface located under the right rays of the sun.

To avoid false response, avoid infrared detector sources of electromagnetic waves, wind and thermal flows.

Discovery zone

When choosing a suitable installation site, take into account the object detection zone with different placement of the device

It is also impossible to fall into the zone of action - a gradually cooled thread will lead to a detector response, since it will respond to the inclusion of its temperature.

So it can continue until infinity - the light will turn on and off. False response can also occur in windy weather due to branches.

Sensor work

When choosing a place of installation and location of the sensor itself, it is necessary to consider: installation height, ambient temperature, make sure there is no no interference

How to install the device and connect it to the lamp?

To begin with, consider the installation of the motion sensor on the example of models that are installed in the holes intended for point lamps.

Installation sequence Next:

  1. Turn off the voltage in the power grid.
  2. Remove the protective plastic lid (Fig. 1).
  3. Connect the conductors (Fig. 2). Connection diagram The manufacturer indicates the instrument itself and in the device passport.
  4. Figure springs-locks, directing them up (Fig. 3).
  5. Install the sensor in the prepared hole (Fig. 4) - the springs will fix its position.

Installation can be considered completed. It remains to adjust and test the operation of the device.

Sensor connection circuit

Motion sensors in the mounting of motion sensors that are installed in the holes for point illuminators are indicated on the back side. It can be somewhat different from different series of devices.

It is easier to establish a sensor that screws into the cartridge. Then the light bulb is screwed into it. In this case, it is necessary to use only those lamps that are not more powerful than indicated in the device passport. It is advisable to purchase, designed to work in a tandem with detectors.

To establish a remote sensor in the ceiling, wall or luminaire case, you must start the device in the prepared hole, fasten the body to the mounting surface with the help of screws. Next, you need to turn off the power supply and connect the phase and zero conductor of the feed cable to the terminals according to the scheme.

Connecting the sensor and marking wires

Before connecting, be sure to check the character of the conductors. Color marking in fact does not always correspond to generally accepted standards

Testing and setting the motion sensor

Each device has a minimum of two regulators. Testing and setting is performed on two main parameters - the duration of the glow (TIME) and trigger sensitivity (LUX). The first indicator means a period of time to which the sensor leaves the lamp turned on.

With each recognized movement, the countdown of the duration of the glow begins first. It can be customized by the user for a period of 10 s to 4 minutes.

The sensitivity of the device is also customizable value. With it, it can be corrected, with what kind of natural lighting will be turned on. Thus, you can adjust the inclusion of the lamp during and day, and the night or only at night.

Running the motion sensor to work, carry out its mandatory testing. To do this, set the light level control to the day lighting position. The time control regulator is set to minimum.

After connecting to the power, you need to wait about 30 seconds - the sensor will work and turn on the lighting also for 30 seconds. Next, you should send a sensor sensor to the zone that should be under observation, check the sensitivity and radius of action.

Testing whether the interval of the response time and the lamp operation with the parameters set. You also check the operation of the device at night and finally set comfortable parameters for yourself.

More complex device designs, which are used in security purposes, have in their design yet regulator of the range (SENS). With it, the sensitivity zone is set. Sensors also equip the integrated microphone with the noise level control (MIC), in which the device must work.

The last two regulators are rarely used for inexpensive sensors, since their functionality in domestic conditions is rarely in demand.

Options for connecting the IR device to the lamp

Using various connection schemes and additional devices, you can achieve a wider functionality of the motion sensor. For example, expand the controlled zone, turn off the automatic control of the lighting system or temporarily control the lighting group without the participation of the motion sensor, etc.

Connection to control without switch

A diagram consisting of a lamp and detector is the simplest. It is applied by the manufacturer on the back of the device or is described in the attached instruction.

Simple connection scheme

The simplest connection scheme solves the main task - turning on the lamp when driving motion in the control zone

When arranging elongated premises, along the tracks in the yard or around the perimeter of the building of one device, it is not enough to control the lighting - its limited review does not allow this to do.

In such cases, two or more detector use. Their terminals are connected by parallel diagram, and then lead to the lamp.

Scheme with two sensors

Connection diagram with two detectors: when you trigger any of them, the contact in the power gross is closed and the lamp lights up

Connecting to the light bulb with switch

To disable the automatic switching system, which runs on the basis of the motion detector, a switch is added to the working circuit. Connect it on a plot of an incoming power cable before the sensor.

In the enabled position of the switch, the scheme works just as if it was drawn up without it. When it is turned off, the motion sensor module is completely de-energized and the system does not work.

Connection diagram with switch

One of the options for organizing a connection circuit with a switch: when the contacts are blurred, the system completely stops working

If it is necessary that when a person is located in the room, the light burned, while finding it in a fixed posture did not lead to the disconnection of lighting, then use the following scheme.

The switch is connected to the input and output phase conductor of the sensor - thus, a branch of the electrical network is created bypassing the main area. Now, using a switch, you can enable lighting that will not depend on motor activity in the controlled zone.

Another scheme with a switch

In this scheme, the switch is shut down the electrical circuit plot through the lighting control sensor. This connection creates more comfort when controlling the lighting device.

Tested in practice the circuit of connecting the lighting control device using the switch disassembled and, read which we really advise.
