Raindrops Detection Sensor Module

The Raindrops Detection Sensor Module is a reliable tool for identifying rain presence or moisture levels, making it ideal for weather monitoring, smart irrigation, and outdoor automation systems. It detects rainfall using a corrosion-resistant PCB with exposed lines that register conductivity changes when wet, sending digital or analog signals to microcontrollers like Arduino, ESP32, or Raspberry Pi.
