Rain Sensor
Technical Overview
The Rain Sensor Module is a reliable, high-sensitivity weather detection interface designed for automated rain detection, ambient moisture monitoring, and environmental telemetry systems. Built with a dual-sided nickel-plated detection board and a high-precision LM393 comparator IC, this module detects water droplets and surface precipitation through changes in electrical conductivity. Featuring dual output modes, it provides an analog output (AO) for measuring rain intensity and a digital output (DO) for direct threshold-based triggering. Operating on a standard 3.3V to 5.0V range, it offers seamless plug-and-play compatibility with Arduino, ESP32, and Raspberry Pi—making it an ideal choice for automated window closers, smart irrigation setups, and custom weather tracking stations, brought to you by FamePhase Electronic Accessories.
