Raindrops Detection Sensor Module | Rain Water Humidity Sensor

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 for both learning and professional automation systems.
