摘要: An occupancy sensing load control system is disclosed. The includes a detector unit, an occupancy/vacancy signal generator and circuit. unit detects RF signals emitted by cell phones or similar mobile communication devices within area being monitored. generates for the circuit based on detection of qualified absence such predetermined time interval. may also include signal-generating generating pseudo base station zone information neighboring stations transmission to phone in area.
