Liquid Level Controller Module Water Level Detection Sensor Parts ComponentsProduct Image: Product Description: 1.Liquid Level Controller DIY Description : 100% brand new and high quality work voltage:5V controller PCB size:42*69mm sensor PCB size:86*21mm Three color LED indicate low (red), medium (yellow), high (green) water, low water pumping or high-water pumping can be switched on and off when you press the function switch bounce (ie not pressed) when low water relay (external pumps work), start adding water, the water level rises to a high level relay off (pump stopped working) until the water level drops below the low water level again relay again, the above process cycle. This feature is used in automatic water equipment, allowing the water level is maintained at a low level and high level between. When the function switch when pressed, when the high-water relay (external solenoid valve), begins to drain, the water level drops below the low water relay off (solenoid valves stop working) until the water level rises again to the high-water relay pull again, the above process cycle. This feature is used in automatic drainage device, allowing the water level is maintained between low water and high water level. Package Included: 1 x Liquid Level Controller Module Water Level Detection Sensor Parts Components 2. Liquid Level Sensor Features:- 100% Brand New and High Quality- This product is based on the actual needs of the family factories and pumping and the detection of the pool (water tower) to control the water level to achieve control.- With a small, simple wiring, low power consumption, high switching capacity, interference is strong, functional stability characteristics.- Automatically open when you can stably pool (water tower) water pump (solenoid) pumping,automatically stops the pump (solenoid) when full of water.- Local flooding can also be used for automatic rain drainage, such as garages, basements, etcBoard Size: 7cm x 4cm(L*W)Material: Electronic ComponentsThe product does not need to buy another probe, using household wiring can replace probeNote: - The probe is a wire mesh shell with a plastic buckle up the thread, with household wires can be directly induced, strip off the head of wire about 2cm, making it bare to direct inductionAnother: The product does not include line (probe)- Lighting, display and other factors may cause COLOR SHADING, please comprehensive pictures and text descriptions to determine!
