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

 

Soil moisture module is sensitive to the ambient humidity and is generally used to detect the moisture content of soil. The Digital Out port will set to high when the the soil humidity exceeds a set threshold value.
The digital output can be connected directly to an Arduino to detect high and low by the microcontroller to detect soil moisture. The digital outputs DO can directly drive the buzzer module, which can be used as 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 sent to an Arduino.
