Soil/Dust Humidity/Water/Moisture Sensor

  • This is a simple water sensor can be used to detect soil moisture when the soil moisture deficit module outputs a high level, and vice versa output low. Use this sensor produced an automatic plant watering device, so that the plants in your garden without people to manage.
  • Sensitivity adjustable the blue digital potentiometer adjustment
  • Operating voltage 3.3V-5V
  • Module has digital output for more accurate.
  • With fixed bolt hole for easy installation
  • Small board PCB size: 3cm * 1.6cm
  • Power indicator (red) and digital switching output indicator (green)
  • Comparator LM393 chip, very stable



  • VCC  connect to 3.3V-5V
  • GND  connect to GND
  • DO   digital value output connector(0 or 1)
  • AO  analog value output connector



  • Soil moisture module is most sensitive to the ambient, generally used to detect the moisture content of the soil.
  • When the module can not reach the threshold value, DO port output high, when the the soil humidity exceeds a set threshold value, the module D0 output low;
  • The small board digital output D0 can be connected directly to the MCU, MCU to detect high and low, to detect soil moisture;
  • Small board digital output DO can directly drive the buzzer module or relay module in our store, which can form a soil moisture alarm equipment;
  • Small board analog output AO and AD module connected through the AD converter, you can get more precise values ​​of soil moisture;


Shipping including:

  • Sensor probe
