Patent ID: 8430337

Claim:
A portable fluid mist sprayer system for use with an aerosol container having an internal valve and containing a treating fluid, the system comprising: a housing with a dome and a dome base, wherein the dome is rotatable relative to the dome base to selectively adjust a direction of spray; a self-contained electrical power source; at least one spray nozzle and at least one ambient light sensor disposed in the dome, wherein the at least one spray nozzle is rotatable with the dome relative to the dome base; the at least one spray nozzle being configured to receive the treating fluid from the aerosol container and selectively discharge the treating fluid in the form of a mist; at least one flow conduit providing fluid communication between the aerosol container and the at least one spray nozzle; a motor adapted to selectively actuate the internal valve in the aerosol container; and an electronic control unit programmed to activate the motor to initiate a flow of pressurized treating fluid to the at least one sprayer head in response to sensed ambient light of predetermined intensity and duration that occur at dusk and dawn; wherein the system is configured to prevent activation of the at least one spray nozzle by transient signals received from the at least one ambient light sensor.
