Motion Detectors

Welcome to High Quality Store Motion Detectors Collection



Is this situation familiar to you? You want to go home but have trouble putting your key in the door because it is too dark. If so, consider investing in a motion detector! This type of switch that triggers automatically when it detects a movement, will make you very useful.


What is a motion detector?

The motion detector uses infrared sensors that react to the thermal radiation emitted by any element that enters its field of vision. Once captured, this thermal radiation is transformed into an electrical signal. If we take the example of lighting control, its most frequent use, the switch will turn on as soon as a person enters his detection zone.

It should not be confused with the presence detector that uses another technology, ultrasound. If it is perfect for indoor use, it is advisable to install your motion detector outdoors. Indeed, less sensitive, it is not likely to light with each passage of flies. In addition, its technology makes it only detect movements during its activation procedure. It therefore does not allow to regulate the light as can the presence detector.

If the motion detector is mainly used to turn on the light, it can in principle control any device such as ventilation, heating and even toilet flushing.


How to choose a motion detector?

There are three things to consider before selecting your motion sensor:

• The detection angle: the larger it is, the wider the area covered. It is generally advisable to take the maximum detection angle that is 360 °. However, if you want to install your detector in a small space, an angle of 180 ° can suffice.

• Transmitting time: This is the time taken by the device to emit a signal once the motion is detected. This can vary from a few seconds to a few minutes. This time, the device turns off the power unless in the meantime a new movement is detected. In this case the timer is reset.

• The detection range: it determines the distance at which the device can detect a presence. It is often between 3 and 12 meters.

It's up to you to choose your motion detector according to the space you have and the use you make of it.


How to install a motion detector?

The installation of your motion detector will depend on the circuit. In this article, we will only focus on the simple circuit. In this case, the detector has three terminals: A, B and C.

• The power must first be taken to the device (terminals A and B) and then go back to the lamp;

• The black wire between the unit and the lamp must then be attached to terminal C;

• The blue wire must finally be connected on one side to the lamp and connected on the other to terminal B.

If you follow these simple steps your detector will have to work properly. Do not hesitate to consult an electrician if you encounter difficulties. Note that it is possible to connect several lamps to the detector, this does not change the procedure.
