  • This is a simple water sensor, can be used to detect soil moisture
  • Module Output is high level when the soil moisture deficit or output is low
  • Can be used in module plant waterer device, and the plants in your garden no need people to manage
  • Instructions for Use: Soil Moisture Sensor
  • Soil moisture module is most sensitive to the ambient humidity is generally used to detect the moisture content of the soil
  • Module to reach the threshold value is set in the soil moisture, DO port output high, when the the soil humidity exceeds a set threshold value, the module D0 output low
  • The digital output D0 can be connected directly with the microcontroller to detect high and low by the microcontroller to detect soil moisture
  • The digital outputs DO shop relay module can directly drive the buzzer module, which can form a soil moisture alarm equipment
  • Analog output AO and AD module connected through the AD converter, you can get more precise values of soil moisture

Interface Description(4-wire):

  • VCC: 3.3V-5V
  • GND: GND
  • DO: digital output interface(0 and 1)
  • AO: analog output interface
