Rain / Raindrop Detection Sensor Kit with Relay Module 2S Positioning 20 Satellites at OpenThe Rain Raindrops Detection sensor module can be used for both detecting rain and for measuring the intensity of rainfall. It includes a printed circuit board (control board) that collects the raindrops. As raindrops are collected on the circuit board, they create paths of parallel resistance that are measured via the op amp. The lower the resistance (or the more water), the lower the voltage output. Conversely, the less water, the greater the output
