Working Principle of Raindrop Detection Sensor Module for Arduino

The raindrop sensor board is a specially designed PCB with exposed conductive tracks. When water droplets fall on the board, they create a conductive path, lowering resistance and triggering a signal change.

The control module, built with an LM393 comparator, processes these signals and outputs both:

• Analog Signal (AO): Represents the amount of water detected, giving proportional readings.

• Digital Signal (DO): Provides a HIGH or LOW signal depending on whether raindrops are detected, with adjustable sensitivity via the onboard potentiometer.

This dual output system allows developers to choose between precise analog measurements or simple digital triggers, making the sensor versatile for different applications.
