Project 22 Soil Module

1.Introduction

This is an easy moisture sensor detecting the moisture of soil. If soil is lack of water, the output analog value decreases; if not, the value increases.

In this project, we use graphical programming to detect analog value of signal port of this sensor, displaying it on serial monitor.

2.Materials Required

1. KEYESTUDIO UNO Control Board *1

2. V5 Sensor Shield*1

3. Soil Module*1

4. Female to Female Dupont Line*3

3.Connection Diagram

4.Sample Code

void setup()
{
  Serial.begin(9600);
}

void loop()
{
  Serial.print("sensorValue:");
  Serial.print(analogRead(0));
  Serial.println();
  delay( 1000 );
}

5.Result

After downloading program, we can use soil module to detect moisture in the soil. Open serial monitor , we can see corresponding value.

This is a printscreen under normal situation.

This is a printscreen when putting soil module into water.
