====PIN Map====

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

====Instructions for Use====

  • The soil moisture module is most sensitive to the ambient humidity and 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 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 soil moisture alarm equipment.
  • Analog output AO and AD module connected through the AD converter, you can get more precise values of soil moisture.
