Product Description
The HS-S09PB Rain Sensor Kit is a reliable rain detection module designed to sense the presence of water or raindrops on its surface. This kit includes a rain sensing board and a control board, allowing projects to determine whether it is raining or wet conditions occur. Operating within a 3.3V–5V supply range, it provides analog and digital signal outputs that can be interfaced with microcontrollers such as Arduino, ESP32, STM32, and Raspberry Pi.
This rain sensor is often used in weather monitoring systems, irrigation control, smart garden automation, outdoor environmental sensing, and IoT weather stations. It sends a high or low signal based on the presence of water droplets on the sensing surface, enabling systems to trigger actions like closing shelters, activating pumps, or sending weather alerts.
