Raindrops Detection Sensor Module (HL-83)
The HL-83 raindrop detection sensor is designed for weather stations, automatic irrigation, window/roof closing systems and any project that reacts to weather.
The set has two parts: the HL-83 comb-shaped board, whose resistance changes when drops land on it, and the HL-01 control module built around an LM393 comparator. Sensitivity is adjusted with the on-board potentiometer.
Outputs: DO — digital (rain / no rain), AO — analog (rain intensity). Supply: 3.3V – 5V, so it works directly with Arduino, ESP32, ESP8266 and Raspberry Pi. In the box: HL-83 sensor board, HL-01 module, connecting wires.
