hey everyone,hope you are doing fine.

here in this video we are going to learn How to make a Rain Alarm Circuit at Home.

Rain Alarm Project is a simple but very useful project that detects Rain (Rain Water) and automatically triggers an alarm or buzzer.

Rain water detector will detect the rain and make an alert; rain water detector is used in the irrigation field, home automation, communication, automobiles etc. Here is the simple and reliable circuit of rain water detector which can be constructed at low cost.

In this project, we have designed a simple Rain Alarm Circuit, which, upon detecting rain, will activate a buzzer. Based on the buzzer, we can take necessary actions.

Things needed to make this Rain Alarm Circuit at Home:-
1) 1x NE555 IC
2) 1x rain sensor
3) 1x BC547 transistor
4) 2x 100k resistor
5) 1x 470E resistor
6) 1x 4.7k resistor
7) 1x 1k resistor
8) 1x 10uf capacitor
9) 1x buzzer
10) 1x 9V Battery
11) connecting wires
