Abstract

A method of operating a dispensing unit includes the step of providing a power source to a dispensing unit that includes a housing having an aerosol container disposed therein and an actuator arm. Other steps include activating the dispensing unit in response to a minimum threshold of light being sensed by a light sensor and selecting a sleep period interval between spray operations. Yet another step includes moving the actuator arm after completion of a startup delay period from a pre-actuation position to a discharge position along a path substantially parallel to an axial length of the container to actuate a nozzle of the container to discharge a fluid from the container. The method also includes the step of alternating automatically between the sleep period having a duration commensurate with the selected sleep period interval and a discharge period during which the fluid is dispensed from the container.
