Abstract:

A circuit for operating a plurality of electrical devices such as lamps for outdoor illumination includes a plurality of motion sensor circuits for detecting motion relative thereto and a plurality of outputs conditioned upon motion detection. Additionally, a photocell sensor circuit for detecting a low ambient illumination level has an output command conditioned upon the detection of a predetermined illumination level that is electrically coupled to the control circuit for illumination of lamps at low ambient lighting levels. The present invention enables the activation of lamps by a plurality of motion sensors having differing fields of view.
