Presence detector
UP 258/21 presence detectors with brightness sensor and constant light level control
The presence detector with a sensing range of 360° allows the automatic execution of control functions in the electrical system by detecting movements. For example, energy consumers can only be switched on if for example people are moving in the сensing range of the 360° presence detector. The energy costs for lighting, heating, ventilation, air conditioning etc. can thus be reduced. The principle of operation of the presence detector essentially corresponds to that of a motion detector. If the optimum assembly location is chosen, the presence detector will also reliably detect people when they are sitting. The front of the presence detector with its pyramid design consists of a large number of small individual lenses. Movements are forwarded to the electronics in the presence detector by means of these lenses, as through a magnifying glass, and evaluated. The presence detector also has a constant light control. When it is dark and when people are present, the artificial light is controlled at a constant brightness according to the amount of daylight available.
