Detailed Description

• ID: grovemoisture
• Name: Grove Moisture Sensor
• Category: liquid
• Manufacturer: seeed
• Connection: analog
• Kit: eak hak

UPM module for the Grove Moisture Sensor. This sensor can be used to detect the moisture content of soil or whether there is water around the sensor. As the moisture content increases, so does the value that is read. Note: this sensor is not designed to be left in soil nor to be used outdoors.

  // Instantiate a Grove Moisture sensor on analog pin A0
  upm::GroveMoisture* moisture = new upm::GroveMoisture(0);
  
  // Values (approximate): 
  // 0-300, sensor in air or dry soil
  // 300-600, sensor in humid soil
  // 600+, sensor in wet soil or submerged in water.
  // Read the value every second and print the corresponding moisture level
  while (shouldRun)
    {
      int val = moisture->value();
      cout << "Moisture value: " << val << ", ";
      if (val >= 0 && val < 300)
        cout << "dry";
      else if (val >= 300 && val < 600)
        cout << "moist";
      else
        cout << "wet";

      cout << endl;

      sleep(1);
    }
