摘要
An occupancy sensor with integral light level sensors is configured to turn off or disable peripheral circuits and go into a periodic deep sleep mode to reduce phantom loading. Peripheral circuits include occupancy sensor circuits and relay drive circuits, but may include other circuits such as communication circuits. The sensor may be configured to periodically wake itself up, check ambient light conditions to see if lighting is below the set threshold. If it is not, the sensor goes back to sleep. If it is, then the sensor can power up the occupancy sensor circuit to see if the space is occupied; if not, it can go back to sleep. If the space is occupied, it can turn on other peripheral circuits necessary to control the load.
