* Soil moisture module is most sensitive to the ambient humidity is generally used to detect the moisture content of the soil.
* Module in the soil humidity less than a set threshold value when the DO port output high, when the when soil humidity exceeds the threshold value is set, the module D0 output low;
* Small plates digital outputs D0 can be directly connected with the microcontroller, microcontroller to detect high and low, and thus to detect soil moisture;
* Small plates digital output DO shop relay module can directly drive the buzzer module, and which can form a soil moisture alarm equipment;
* Small plates analog output AO and AD module connected through the AD converter, you can get more accurate values of soil moisture;
