发明名称 AUTOMATIC PLANT WATERING SYSTEM
摘要 An Automatic Plant Watering System that consists of an electronic twitching system that controls the pumping time of a water pump. The flow rate of the water is controlled by the use of a valve system, which may restrict the flow of the water. The electronic switching is controlled by an electronic humidity sensor which in turn triggers the pump timer. There is a reservoir with a water level float connected to an electronic sensor which inhibits the water pump trigger, to stop water pump operation when the reservoir runs out of water. There is also a nozzle at the end of the water line which may further restrict the flow of water from the system.
