12V Water Level Control Module - Relay Output

 

Automatic water level control relay is a switch module. Using a relay and the input of two sensors (max-limit and min-limit sensors), the water tank level controller can turn devices on and off accordingly. Ideal for applications where the liquid level of a tank needs to be controlled. In such an application, when the liquid level is at minimum, the minimum limit sensor triggers the relay, which starts the pump and fills the tank with liquid. When the liquid level reaches the maximum level, the maximum limit module triggers the relay to turn off the pump.
