Unbelievable Automatic Water Pump Controller Circuit Diagram

Simple automatic water pump controller circuit diagram is a series of functions to control the automatic water pump controller circuit in a reservoir or water storage.

Automatic water pump controller circuit diagram. Automatic water pump level controller circuit with indicator this project is very useful interesting and very effective. Let us consider two reference probes a and b inside the tank where a is the lower limit probe and b is the upper limit probe. Three parts which are a 2n4401 transistor one 1 2k resistor and one dpdt relay.

Automatic water pump controller circuit. There are three probes in the circuit which should be placed in the water and any thin wire will do the job. This automatic submersible motor pump controller circuit with three stage level indicator provides the visual and attractive led indication.

Simplest automatic water pump controller circuit diagram. And it can not only use for controlling water level but you can use it for many other liquids. The circuit will automatically switch on any water pump motor when the level of water in a tank reaches below from the required level and automatically switch off the pump after filling the tank.

As the water level sensor made with a metal plate mounted on the reservoir or water tank with a sensor in the short to create the top level and a detection sensor for detecting long again made the lower level and ground lines. The 12v dc power supply is given to probe c which is the limit for minimum water always stored in the tank. 1 shows the controller circuit.
