Motion sensors:
Motion sensors vs. presence detectors in comparison:
While presence detectors have to respond to the smallest movements, motion sensors are responsible only for monitoring extensive corridors, outdoor areas, or similar spaces. The primary task of motion sensors is to switch the light on when clear movements are detected, whereby this function can be programmed to depend on brightness. Additionally, the light stays on as long as movement is signaled and only switches off again when everything is still. Although the basic principle is identical with presence detectors, a special fine tuning has been made in this design, enabling the light to be turned off again when not needed. The finely mechanical sensor reacts to the smallest differences in brightness and, thanks to a high-resolution detection field, can turn the light on and off at its discretion. A detector that literally thinks along and makes everyday life easier. After all, you no longer have to think about the light. In fact, operating the light switch can be completely forgotten. Or light switches in transitional rooms (hallways, foyers, dressing rooms, staircases) can be completely omitted.
Here the internal construction of the two variants can be seen. The difference is clearly visible. Presence detectors have several PIR sensors. Motion sensors usually only have one.
