Panel PCB Dimension: Approx.3cm x 1.5cm

Soil Probe Dimension: Approx. 6cm x 3cm

Cable Length: Approx.21cm

Interface Description(4-wire):

VCC: 3.3V-5V


DO: digital output interface(0 and 1)

AO: analog output interface

Instructions for Use:

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.
