Rain Drop Sensor Module

Rain drop Sensor Module

The Rain Drop Sensor Module is an electronic sensor used to detect the presence of water droplets or rain. It works by measuring changes in electrical conductivity on a sensing surface when water is present. The module usually consists of a rain sensing board and a control circuit that converts the signal into digital or analog output for microcontrollers like Arduino, ESP32, and Raspberry Pi.

• Module Type: Rain Detection Sensor
• Sensing Method: Conductivity-based (water detection on surface grid)
• Operating Voltage: 3.3V – 5V DC
• Output Type: Analog (AO) and Digital (DO)
• Comparator IC: Often uses LM393
• Sensitivity Adjustment: Yes (via potentiometer on module)
• Detection Range: Detects water droplets, rain, or moisture on sensor plate
