A sensor circuit for remotely commanding the operation of a remote device includes a motion sensor circuit for detecting motion relative thereto and having an output 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 a control circuit having a plurality of inputs. The invention further includes a data output comprising a remote device operation command and a transmitter circuit coupled to the data output of said control circuit for transmitting said operation command to a remote device.
