Automatic Water Pump Motor Controller

Hii friend,

Today I am going to make a circuit of automatic water pump motor controller circuit using 2N222 Transistor and relay.

Let's get started,

Components required -

(1.) Relay - 6V/12V x1

(2.) Diode - 1N4007 x1

(3.) Resistor - 220 ohm x1

(4.) Transistor - 2N222 x1

(5.) 230V AC Motor (Here I am using an LED light as load instead of Motor)

(6.) Battery - 9V x1

(7.) Battery clipper x1

(8.) Connecting wires

Connect all components according to this circuit diagram.

Firstly we have to solder Collector pin of transistor to coil-1 pin of the Relay as solder in the picture.

Next we have to connect diode to the circuit.

Solder +ve of diode to coil-1 and -ve of diode to coil-2 of the relay as you can see in the picture.

Next we have to connect 220 ohm resistor to base pin of the transistor as you can see in the picture.

Solder +ve wire of battery clipper to coil-2 of the Relay and

solder -ve wire of battery clipper to emmiter pin of the transistor as you can see in the picture.

Solder a wire in coil-2 of the relay and another wire in 220 ohm resistor as solder in the picture.

Next Cut phase wire of Motor/LED light as cut in the picture (220V appliance).

Now connect cut phase wire to the relay as given in circuit diagram.

Solder a wire to common pin of the relay and solder another wire to NC pin of the relay as solder in the picture.

Connect battery to battery clipper of the circuit.

Now when we will give main power supply to the motor then motor will be start and water will be filling.

As water will fill upto wires then the Motor will be turn off automatically.

As picture shows light/Motor gone turn off automatically when water filled upto the wires.

Thank you
