Motion, Presence & Absence Detection
Presence detectors are ideal for controlling lighting in office spaces as they not only detect large movements but also smaller activities such as people working, so that they are not left in darkness. When the area is left unoccupied the lighting will be switched off thereby minimising the energy usage of the area. Some motion and presence detectors include a photocell which senses natural daylight and can be used to control the lighting during periods of high ambient light, thus avoiding the use of unnecessary energy.
A typical application example for energy savings using motion and presence detectors:
‘In a large commercial building or office complex motion detectors could be installed in the toilet and storage areas, and presence detectors fitted in the office areas.’ with the additional benefit occupancy levels in every area.
