Soil Moisture Sensor Project

The Soil Moisture Sensor project demonstrates how to use an analog soil moisture sensor with an Arduino Mega to monitor moisture levels in soil. This project is essential for applications such as automated irrigation systems, plant health monitoring, and soil moisture studies.

Components Needed

• Arduino Mega
• Analog Soil Moisture Sensor
• Jumper Wires
• Breadboard
• Power Supply

Circuit Setup

Connecting the Soil Moisture Sensor to Arduino Mega:

Instructions

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).

Observe the moisture level percentage readings.

Dip the sensor in water to see the percentage increase, and let it dry to see it decrease.
