An electrical outlet activation and deactivation system includes a controller coupled to a live power source comprising a switch and an RF signal receiver. A remote environmental sensor comprises a motion sensor, a photo cell, and an RF signal transmitter. The motion sensor, detecting a motion, sends a first condition signal coupling the live power source to the electrical outlet or device. The photo cell, detecting a daylight condition, prevents the sending of the first condition signal. A timer uncouples the live power source after a predetermined time has elapsed since the motion sensor last detected the motion. A regulator couples and uncouples the live power source to the electrical outlet or device independent of the sensor. The controller can include an electrical plug removably connectable to the live power source through an electrical outlet, or alternatively, can be permanently coupled to the live power source through a hardwire connection. |
