<p num="1"><br/>A sensor circuit for remotely commanding the operation of a remote device <br/>includes a <br/>motion sensor circuit for detecting motion relative thereto and having an <br/>output <br/>conditioned upon motion detection. Additionally, a photocell sensor circuit <br/>for detecting <br/>a low ambient illumination level has an output command conditioned upon the <br/>detection <br/>of a predetermined illumination level that is electrically coupled to a <br/>control circuit <br/>having a plurality of inputs. The invention further includes a data output <br/>comprising a <br/>remote device operation command and a transmitter circuit coupled to the data <br/>output of <br/>said control circuit for transmitting said operation command to a remote <br/>device.<br/>
