Introduction
Ever rushed home to collect clothes drying outside because of sudden rain? Tired of manually checking if your garden needs watering or if your car’s wiper needs adjustment? The MH-RD Raindrops Module is here to automate rain detection—keeping your belongings dry, your plants healthy, and your life hassle-free.
What is Raindrop module？
A raindrop sensor is a sensor used to detect the presence and intensity of rain. It usually consists of a metal plate and a sensor module. The module detects changes in the surface resistance of the metal plate to determine whether rain drops are falling, thereby achieving the perception of rainfall conditions.
