Objective

This experiment demonstrates the use of sensors to detect nutrient levels in soil.

Components Required

• Soil Nutrient Sensor
• Arduino Board (e.g., Arduino Uno)
• Jumper wires
• Breadboard

No Ads Available.

Working Principle

The soil nutrient sensor detects the levels of nutrients like nitrogen, phosphorus, and potassium in the soil by measuring electrical conductivity.

Circuit Diagram

Code

/*
 * Soil Nutrient Detection
 * This code reads soil nutrient levels from the soil sensor.
 */

const int sensorPin = A0;  // Soil sensor connected to analog pin A0
int sensorValue = 0;

void setup() {
  Serial.begin(9600);  // Initialize serial communication
}

void loop() {
  sensorValue = analogRead(sensorPin);  // Read the sensor value
  Serial.print("Soil Nutrient Level: ");
  Serial.println(sensorValue);
  delay(1000);  // Wait for 1 second before the next reading
}
            

Results

The serial monitor will display the nutrient level readings.
