Abstract

An occupancy sensor detects expected and unexpected occupancies in a monitored area with an expected occupancy schedule. The occupancy sensor includes a real time clock, a memory, a sensor element, a processor, indicator lights and a network interface. The occupancy sensor transmits an occupancy correction signal to a network if the actual occupancy of the monitored area does not match the expected occupancy state of the monitored area.
