Description

The Raindrops Detection Humidity Sensor Module is a simple and reliable device used to detect rainfall, water splashes, or humidity levels on a surface. It consists of a rain detection board and a comparator module that converts analog moisture levels into a digital output signal . This sensor works perfectly with Arduino, Raspberry Pi, ESP32 , and other microcontrollers to trigger actions such as closing windows, activating alarms, or controlling motors in smart home and IoT projects. With a wide operating voltage range (3.3V–5V) and adjustable sensitivity , it provides consistent and accurate water detection even in outdoor environments. The module is compact, easy to integrate, and ideal

Key Features
