Abstract
An occupancy sensor may control a load in response to its own operating conditions. In some embodiments, the occupancy sensor may include an energy storage device to operate the occupancy sensor when a load it controls is not energized. The occupancy sensor may energize the load to transfer energy from the load to the occupancy sensor when the amount of energy stored at the occupancy sensor reaches a threshold level. In some other embodiments, the occupancy sensor may include two sensing circuits and a connection to transfer energy from a load it controls to the occupancy sensor when the load is energized. The occupancy sensor may disable one of the sensing circuits when the load is not energized.
