Interface Description (4-wire):
DO: digital output interface (0 and 1)
AO: analog output interface
Directions for Use:
Soil moisture module is most sensitive to the ambient humidity is in most cases used to notice the moisture content material of the soil.
The digital output D0 can also be related in an instant with the microcontroller to notice high and low with the aid of the microcontroller to realize soil moisture.
The digital outputs DO retailer relay module can immediately power the buzzer module, which is able to type a soil moisture alarm gear.
Analog output AO and AD module connected through the AD converter, you can get more precise values of soil moisture.
