Learn more about presence detectors: Technology, detection area and light measurement
Presence detectors work according to thesame principle as motion detectors: They detect thermal radiation in their surrounding, that is in their detection area. If thermal radiation is detected in the detection area, for example caused by a person approaching the presence detector, the presence detector converts the radiation into a measureable, electric signal, and the light is switched on.
Technology: How does a presence detector work?Presence detectors work according to the same principle as motion detectors: They detect thermal radiation in their surrounding, that is in their detection area. If thermal radiation is detected in the detection area, for example caused by a person approaching the presence detector, the presence detector converts the radiation into a measureable, electric signal, and the light is switched on.

Light measurement with presence detectors: Constant light control or mixed light measurement?Lighting control using presence detectors is based on detected movement on the one hand and on light measurement on the other. Presence detectors permanently measure the brightness inside the room. Through this permanent light measurement, the presence detector is able not only to switch on artificial light when there is not enough daylight, but also to switch it off again when there is sufficient daylight. It sounds very easy, but in fact the presence detector must be able to assess, whether there is enough daylight after switching off the artificial light. Light measurement with presence detectors |
Advantages of the square 360° detection areaAs most rooms are square or rectangular, a square detection area simplifies planning enormously. The detection areas of the individual presence detectors can be lined next to each other with no gaps. In addition to simplified planning, there is another practical benefit: There are no "blind spots" or overlappings in the room. And movements are guaranteed to be reliably detected everywhere.

Planning and installation: Correct installation of presence detectors
Those who want to position the light correctly right from the start will benefit from the Relux light simulation, which in general is free of charge. Relux offers professional planning software for development and |
Practical advantages of presence detectorsDue to their very fine sensor technology, Theben presence detectors detect even smallest movements and temperature differences. In this way, they allow to exactly adjust light and climate to the needs of inhabitants and users. Depending on the model, the various presence detectors are available in the colours black, white, grey, silver or in special colours upon request.
