ARDUBLOCK Project 22: Soil Module

Posted by Fiona Su on April 12, 2020

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.
Materials Required:

1. KEYESTUDIO UNO Control Board *1
2. V5 Sensor Shield*1
3. Soil Module*1
4. Female to Female Dupont Line*3

Connection Diagram:

After wiring, we can start programming.

Click “download to Arduino” to see the following codes in IDE interface:
Sample Code:

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

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

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.
