It’s difficult to detect some changes in weather conditions, and rainfall is one of the most unpredictable meteorological characteristics. So we decided to interface the Raindrops sensor with an Arduino in this tutorial. The raindrop sensor, often known as the rain detector sensor, is a simple device for detecting rainfall. When raindrops fall on the sensor, it operates as a switch. But, with minor code changes, it can also monitor the intensity of the rainfall. This sensor additionally contains a separate indicator light and an integrated potentiometer for adjusting the sensitivity of the sensor’s output digital signal.
