Rain Drop Sensor

The Rain Drop Sensor project demonstrates how to use an analog raindrop sensor to detect rain. The sensor provides an analog voltage output that varies based on the presence of water droplets on its surface.

Circuit Setup

Connect the Rain Drop Sensor to Arduino Mega:

Instructions

Circuit Setup:

Connect the raindrop sensor to the Arduino Mega as described in the circuit setup section.

Library or Dependencies:

No additional libraries are required for basic analog sensor interfacing.

Code Upload:

Open the Arduino IDE and create a new sketch.

Copy and paste the provided Arduino code into the sketch.

Upload the code to the Arduino Mega.

Testing:

Open the Serial Monitor in the Arduino IDE (set to 9600 baud) to monitor the sensor readings.

Observe the sensor value and corresponding messages indicating "It's raining!" or "No rain detected."
