Make Water Overflow Alarm easily at home 

Welcome to the Technical Praveen, In this article, we will learn how to make a Water level indicator at home. if you wanna learn how to make it carefully read the full article. this is the most interesting and popular project nowadays in electronics and engineering, many of the students from college and school making this awesome project. the interesting thing is that this is the cheapest water level indicator. We will learn how to make circuit diagram.

Circuit Diagram :

Components required :

1) Mobile Charger

2) Buzzer

3) LED

4) Wires

How to make Water overflow alarm :

1) firstly connect positive terminal of charger to positive end of led and buzzer.

2) Negative end of charger goes to directly on the tank.
