Abstract
An occupancy estimation system is provided. The occupancy estimation system is configured to estimate a number of occupants in a target space. The occupancy estimation system includes a PIR motion sensor and a control apparatus. The PIR motion sensor is with a field of view of an area where occupants are expected to be present, and the PIR motion sensor is adapted to output a PIR signal. The control apparatus is adapted to receive the PIR signal to compile an aggregate of the minor and major motion behaviors of the occupants in the field of view and generate an occupancy estimation count accordingly.
