An occupancy sensor reliably detects if persons are present in a room. It automatically turns lights (or other consumers) on when a room is occupied and off when a room is vacant. To achieve this, the sensor needs to pick up fine movements without false triggerings. Normal motion sensors are not suited for this. Although simple in concept, occupancy sensing is probably the single most effective energy saving strategy. Energy saving could not be easier!
Available are ceiling-mounted occupancy sensors as well as occupancy sensors for luminaire integration.
