how to make a rain alarm sensor
Рет қаралды 8,106
6 жыл бұрынwe are making a rain alarm sensor that will turn on an LED and a buzzer When the rain comes.Enjoy it.
Rain alarm or rain alarm sensor is used to detect rain.The Project is a simple but very useful project that detects Rain (Rain Water) and automatically triggers an alarm or buzzer and also turns on an LED.
In this project, we have designed a simple Rain Alarm Circuit, which, upon detecting rain, will activate a buzzer a turning on an led. Based on that, we can take necessary actions.
All the components and connections are given step by step in the video.
Thank you for watching our video.
