Raindrops Detection Sensor Module

Overview

A rain/moisture detection module — a conductive sensor plate that changes resistance when wet, paired with a comparator board for analog and digital output.

Key Specs

Pinout

VCC, GND, AO (analog out), DO (digital out)

Features

• Adjustable sensitivity via onboard potentiometer
• Analog output can indicate rain intensity, not just presence

Compatible With

Arduino, ESP32, ESP8266, Raspberry Pi

Use Cases

• Automatic rain-shield/clothesline protection projects
• Weather station rain detection

FAQ

Does the sensor plate corrode over time? Prolonged wet exposure can affect any exposed-conductor sensor eventually — keep it dry when not in active use for longer sensor life.
