AJMRTC raindrop detection sensor module is designed for rainfall and humidity monitoring. The module consists of a rain-sensing probe and a main control board. When raindrops fall on the probe surface, the resistance changes and generates corresponding analog voltage signal, which reflects the rainfall intensity. Meanwhile, it provides digital switching output to judge whether it is raining. Users can adjust detection sensitivity through the onboard potentiometer. Operating at DC 3.3V-5V, it works seamlessly with Arduino, Raspberry Pi and most single-chip microcontrollers. The split structure allows you to place the probe in exposed outdoor areas while keeping the circuit board protected indoors. It is widely applied in smart window automatic control, weather station data collection, agriculture irrigation reminder and rain alarm DIY electronic projects.
