Patent ID: 7345270

Claim:
A photocontrol, comprising: a housing; a light sensor carried by said housing, said light sensor sensing an ambient light level outside said housing and emitting a signal indicative of said ambient light level; a microprocessor carried by said housing and in operative connection with said light sensor so that said microprocessor receives said signal indicative of said ambient light level sensed by said light sensor, said microprocessor emitting a first output signal when said ambient light level reaches a first preprogrammed level and a second output signal when said ambient light level reaches a second preprogrammed level; an antenna carried by said housing; a radio receiver carried by said housing and responsive to said antenna, said radio receiver for receiving a radio signal from a source via said antenna, said radio signal carrying coded current date and time information; a decoder carried by said housing and in operative connection with said radio receiver, said decoder for extracting said coded current date and time information from said radio signal, said decoder sending current date and time information to said microprocessor when said decoder extracts data and time information from a radio signal; and a first switch, carried by said housing and in operational connection with said microprocessor, for inputting a time at which said microprocessor is to emit said second output signal regardless of said ambient light level.
