Arduino Uno Raindrop Sensor

This project utilizes an Arduino Uno and a raindrop sensor to detect rainfall.

It reads the analog output from the sensor and prints a message to the Serial Monitor indicating whether rain is detected based on a predefined threshold.

Components Needed

• Arduino UNO
• Raindrop Sensor
• Jumper Wires
• Breadboard

Hardware Wiring Explanation:

Connect Raindrop Sensor to Arduino Uno:

Connect the analog output of the raindrop sensor to analog pin A0 on the Arduino Uno.

Ensure the sensor's VCC pin is connected to +5V and GND to GND on the Arduino.

Wire up the raindrop sensor to the Arduino Uno according to the circuit setup section.

Software (Arduino IDE):

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 Uno.

Project Operation:

Open the serial monitor with a baud rate of 9600.

Observe the output on the Serial Monitor, which will indicate "It's raining!" when the sensor detects rain above the defined threshold.

Applications

Notes

Adjust the

Ensure the sensor is positioned correctly to detect raindrops effectively.

Customize the code to integrate additional features such as data logging or real-time alerts as needed.
