Sense motion, detect movement and save energy

PIR (Passive Infrared) presence detectors detect body heat and movement and are ideally suited where a defined detection pattern in required.

Our range of PIR sensors are designed to reduce the amount of time lighting is left on unnecessarily, for example if an area is unoccupied or if there is sufficient natural light.

A presence detector monitors the detection zone for occupancy; if a person is sensed then the detector will automatically turn the lighting on. When the area is vacated, the lighting will turn off after a preset time delay. Most of our PIR sensors have a built in light level (lux) sensor which will keep the lighting off if there is enough natural light available.
