The rain sensor module is a two-part resistive detection system that senses the presence and intensity of rainfall by measuring the change in electrical conductivity across a set of interleaved nickel-plated copper traces on an exposed sensing board. As raindrops bridge the traces, resistance drops and the analog output voltage changes proportionally — the wetter … Read more
