Product includes:

  • 1pcs X High Quality Soil (Moisture) Sensor Module
  • 1pcs X Sensor Probe


  • +:connect the power supply postive port
  • -:connect the power supply negative port.
  • After connected the power supply, the “P” indicator will light up and the module will work.
  • Regulator the blue potentiometer to regulate the sensor sensitivity. If the set the values as 0.1, regulate it in CW direction means when the moisture is lower than 0.1 will trigger module, if in CCW direction, and detected signal higher than 0.1 will trigger module.
  • if regulator the potentiometer lead to the “S” indicator light up means the the regulated values is over the testing limit values[คุณภาพสูง] High Quality Soil (Moisture) Sensor Module
