OCCUPANCY DETECTION SYSTEM

摘要

A presence determination system comprising at least one motion sensor for detecting movement in a sensing area. The system is adapted to determine a plurality of properties associated with at least one movement detected by the at least one sensor preceding a period where no motion is detected by the at least one sensor. The plurality of properties of the movement(s) detected before the period where no movement is detected are compared with a profile in order to determine whether or not the sensing area is unoccupied. The profile may be representative of movement properties indicative of exiting a room.
