RAIN ALARM PROJECT

Rain Alarm Project for School Science Exhibition | Step-by-Step Tutorial









Description:

In this video, learn how to make a Rain Alarm Project without using Arduino — perfect for your school science exhibition or science fair! 🌦️
This simple project uses a rain sensor circuit made with basic electronic components to detect rain and automatically turn on a buzzer or LED when water drops fall on the sensor. 💧🔔

No Arduino or programming is required — just a few simple components and a clear step-by-step explanation that anyone can follow!

Components Required:-

Rain Sensor 
Really Module 
Breadboard 
Jumper Wires 
5v Buzzer 
Lithium Battery 





Working Principle:

When water droplets fall on the rain sensor plate, the circuit gets completed and activates the transistor.
This allows current to flow to the buzzer or LED, producing an alarm that indicates rain has started.
