Patent ID: 7886483

Claim:
An electronic device for warning of low water in a tree base comprising: a voltage regulator circuit which receives electrical power from a power supply; a flasher unit; a timing circuit; a voice recorder; a microphone to record sound into the voice recorder; a float switch which triggers a first relay to activate the flasher unit and the timing circuit, wherein the flasher unit triggers a second relay which opens and closes a hot power lead connected to a flasher outlet within the electronic device; a lighting device in electrical connection with the flasher outlet within the electronic device; a voice recorder circuit activated by a third relay controlled by the timing circuit; and, a housing to enclose the circuitry and protect it from damage; wherein the float switch triggers the first relay which turns the flasher unit on when the water level in the tree base is low and off when the water level in the tree base is sufficient; wherein the flasher unit, powered by the closure of the first relay, triggers a second relay to periodically open and close causing a circuit containing the hot power lead to the flasher outlet to periodically open and close; wherein the float switch triggers the timing circuit which triggers the third relay to periodically open and close at a set interval, which triggers the voice recorder to periodically turn on and off to play back a recorded message when the water level in the tree base is low.
