Introduction: How to Make Over Water Flow Alarm Circuit Using Z44N MOSFET

About: Share diy projects to those who have the same hobby with me

Hii friend,

Today I am going to make a circuit of over flow water alarm.Basically this circuit we can use to know the over flow of water of our water tank.we will make this project using IRFZ44N MOSFET.

Let's get started,

Step 1: Take All Components As Shown Below

Components required -

(1.) Buzzer x1

(2.) MOSFET - IRFZ44N x1

(3.) Connecting wires

(4.) Battery - 9V x1

(5.) Battery clipper x1


This picture shows the pins of this MOSFET.

G - Gate

D - Drain and

S - Source

Step 3: Connect Buzzer to Mosfet

Firstly we have to connect buzzer to the MOSFET.

Solder -ve pin of buzzer to Drain pin of the MOSFET as solder in the picture.

Step 4: Connect Battery Clipper Wire

Next solder Battery clipper to the circuit as shown in the picture.

Solder +ve pin of the Battery clipper to the +ve pin of buzzer and

solder -ve pin of battery clipper to Source pin of the MOSFET.

Step 5: Connect Wires

Now we have to connect wires in the circuit.

Solder a wire to the Drain pin of the MOSFET and

again solder a wire to the Gate pin of the MOSFET as solder in the picture.

Step 6: Circuit Is Ready

Now our circuit is ready so connect battery to the battery clipper and

Put wires of Drain and Gate in the upper side of tank and fill water.

Step 7: How Circuit Works

As water will be full contact to the wire then buzzer will start giving sound.

and we can do silent of buzzer by opening the battery.

This type we can make over flow water alarm circuit.
