How to connect a motion sensor to light ?

Before you move on to how to connect a motion sensor to light his own hands, it should be noted that the device in question - it is not the same as the ambient light sensor, which we have already discussed in a previous article.This product is designed for instant switching of light in contact with an object in the detection zone.To learn how to install and connect the motion sensor will be discussed later!

What is the working principle?

Many wonder exactly how the detector.To readers of "electrician himself" were fully aware at first quickly go over the basic principle of the sensor action.Automatic street lighting

Activation and inclusion of the lamp will depend on what type of detector you choose.To date, the following types of motion sensors for lighting:

  • sound - trigger on the noise level in the detection area;
  • vibration - short circuit if they find near the moving object;
  • infrared - react to heat.

For outdoor use it is best to install a second version of the motion sensor, which is also suitable for use in the apartment (entrance).The remaining two options are more commonly used in security systems.As to the operating principle, everything is not difficult - the detector upon detection of the object (or sound / increasing temperature) gives a signal, whereby the relay closes the circuit and is switched on the light bulb.

way a simple detector can be made with your own hands, unless of course have the slightest skills with a soldering iron.If there was interest in creating such a useful homemade, we recommend to view video tutorial provided below.

Ways to connect to a network

Second, an important caveat that you need to know - wiring diagram of the motion sensor to light.To date, the device can be connected directly to the lamp, through a conventional switch or in combination with another detector established elsewhere.

To your attention the four variants of the wiring terminals:

By the way, it is not necessary to display a new line from the junction box, creating additional Stroebe wall.Apparatus for lighting control can be connected to a power outlet by plugging the power cord with a plug or "embed" directly to the place of connection to the electric chandeliers.current models running on batteries (wireless) is also there.

With regard to the first circuit connecting the motion sensor, it is the most simple, but at the same time and the least convenient to use in the house and the apartment, becausethe light will be switched on only when detection occurs.The second option is more convenient, because it is possible to switch the circuit breaker on the normal keyboard.In this case, the current will flow to bypass the detector, which will make permanent lighting in the room as long as not to open the circuit breaker manually.

electrical circuit with the magnetic actuator used in the event that you decide to connect to the Detector powerful light sources, for example, a few spotlights.The fact that one of the characteristics of the sensor is nominal power, which usually ranges from 500 to 1000 watts.If the total wattage of the light source is greater than the characteristics, it is necessary to add a magnetic contactor circuit.

Last connection method used in the event that it is necessary to monitor the spacious room or winding corridor.This is due to the fact that the maximum conventional device coverage does not exceed 12 meters (expensive current models can detect the object and within 20 meters).If you want to monitor a large area, for example, the garden at the cottage, which will be highlighted by a street lamp, a detector is not enough and the area is only partially under control.The same situation is with the winding corridor, in which you choose to install a motion sensor lighting.Each turn is a barrier behind which the control will not be carried out.It is therefore to trigger occurred, and thus the inclusion of light at several points have to be connected detectors.

Installation Instructions

with mounting scheme and the principle of operation of the device, we have understood.It remains the last and most importantly - provide a motion sensor connection technology for lighting.Disassemble the cabinet with terminal blocks

So, to connect a motion sensor to the network 220 in your hands, you should perform the following steps:

  1. Determine the wiring diagram.
  2. Choose the most suitable place to install the detector.Most often, the housing is mounted in a corner or on the ceiling.If you have decided to carry out installation of the street, there is already need to act according to circumstances.The main factor - the angle of the sensor viewing.You have to choose the most optimal place housing accommodation, to minimize any dead zone.Usually used for this purpose bearing wall construction, or a street lamp support.
  3. Turn off electricity at the opening panel, asYou'll have to deal with the introductory bare wires from the network.
  4. According to the chosen scheme, connect 3 wires to the terminals on the sensor housing (they can be seen in the photo above) and the lamp.Observe the color-coded wires and lean on the designation of the connectors, so as not to confuse the core.Reverse phase and zero you will not only do harm to the wiring, but you can and expose his life to danger, so be careful.
  5. Adjust the controls on the body, so that they are in optimal positions.The front of the motion sensor, you can see up to four primary regulators: «LUX» - the light level at which the trigger, «TIME» - off delay time light after the discovery, «SENS» - device sensitivity to triggering, «MIC» (It occurs not in all models) - Adjusts the noise level that pi circuit fault occurs.All of these controls should be adjusted in the individual case.For example, why light detector will turn on the lights during the day, or as much as 420 (the maximum setting), if you can set fire only at night, for 10 seconds at the same time, if it is a person, not a cat or other small object (for example for outdoor use).Regulators on the body
  6. including power on the board and move on to testing, you may have to change the settings or the location of the product.


That's the step by step instructions for installation of the detector!We hope that you now know how to install and connect a motion sensor to light his own hands!To help you see clearly the essence of the event, this offer video instructions:

Finally I would like to give a couple of tips on installing and connecting the motion sensor lighting.Firstly, it is desirable to place the products away from the housing of devices that emit electromagnetic waves, asthey can trigger a false alarm.Second, often wipe dust from the lens, sinceany contamination will adversely be displayed on the operation efficiency of the system.And thirdly, if you decide to connect the detector in the country, place it away from trees and shrubs, which will also be a hindrance!
