Abstract: The presence detector has a passive infrared sensor for detecting the presence of persons in a room, an image sensor operating in the visible spectral range and an electronic evaluator for the evaluation of signals from these sensors. The signal from the passive infrared sensor is used to actuate the image sensor and, if necessary, to switch on the room lighting. Once activated, the image sensor is used to detect both movement and occupancy of a space being monitored. Application of the presence detector for the nullon-demandnull activation and/or control of conditioning facilities of a room, wherein the signals of both sensors are used for the control of the conditioning facility.
