Circuit Setup

Connect Soil Moisture Sensor to Arduino Nano:

Connect the VCC pin of the soil moisture sensor to the 5V pin on the Arduino Nano.

Connect the GND pin of the soil moisture sensor to the GND pin on the Arduino Nano.

Connect the A0 pin of the soil moisture sensor to analog pin A0 on the Arduino Nano.

Instructions

1.Circuit Setup:

Wire the soil moisture sensor to the Arduino Nano as described in the circuit setup section.

2.Code Upload:

Open the Arduino IDE and paste the provided code.

Upload the code to the Arduino Nano.

3.Testing:

Once the code is uploaded, open the serial monitor.

The serial monitor will display the soil moisture level in percentage and indicate whether the soil is wet, moist, or dry based on predefined thresholds.

Applications

agriculture: Monitor soil moisture to optimize irrigation and improve crop yield.

gardening: Ensure proper watering of plants by monitoring soil moisture levels.

Environmental Monitoring: Use soil moisture sensors in environmental monitoring applications to assess soil conditions.

Notes

Calibrate the soil moisture sensor if necessary to ensure accurate readings.

Adjust the predefined moisture level thresholds in the code based on the specific requirements of your application.

Consider integrating the soil moisture sensor with actuators to automate irrigation systems based on soil moisture levels.
