Water Drop Rain Sensor Module – Moisture Detection for Arduino

Description The Water Drop Rain Sensor Module is designed to detect the presence of water or rain using a corrosion-resistant sensor pad. It provides both analog and digital outputs, making it easy to interface with microcontrollers like Arduino, ESP32, or Raspberry Pi. The module includes an amplifier board with a comparator and sensitivity control potentiometer. It’s widely used in weather monitoring systems, automatic wiper controls, and smart irrigation projects. Features: Separate sensor pad and control board Analog (A0) and digital (D0) outputs Adjustable sensitivity using onboard potentiometer Water- and corrosion-resistant sensing surface LED indicators for power and output state Supports both 3.3V and 5V logic systems Easy to integrate with microcontrollers Specifications: Sensor Type: Rain/Water drop detection Operating Voltage: 3.3V – 5V Output Type: Analog (A0), Digital (D0) Interface Pins: VCC, GND, A0, D0 Sensing Surface: Nickel-plated PCB Dimensions (Sensor Pad): Approx. 50mm x 40mm Dimensions (Module): Approx. 32mm x 14mm Sensitivity: Adjustable (via potentiometer) Package Includes: 1 x Rain Sensor Pad1 x Control Board1 x Connecting Cable
