Abstract

A power source is provided to a dispensing unit that includes a housing having an aerosol container disposed therein. A sleep period interval between spray operations is selected and a motion sensor is activated to detect motion within a sensory path of the sensor after completion of the sleep period interval. If no motion is detected by the motion sensor a fluid is automatically discharged from the aerosol container and the sleep interval is reset and if motion is detected by the motion sensor a delay time interval is initiated and fluid is not discharged from the aerosol container. The dispensing unit alternates between activating the sensor to detect motion and resetting the delay time interval until no motion is detected by the motion sensor at the expiration of the delay time interval, which results in the automatic discharge of fluid and a resetting of the sleep period interval.
