Instructions

A soil moisture and humidity module most sensitive to the environment,usually used to detect soil moisture .

Modules in the soil moisture reach the set threshold,DO port output high when soil moisture exceeds a set threshold,the module D0 output low ;

Digital outputs D0 small plates can be directly connected with the microcontroller through the microcontroller to detect high and low,thereby detecting soil moisture ;

Small plates digital output DO OUR relay module can directly drive the buzzer module,which can be composed of a soil moisture alarm equipment ;

Small plates AO analog output modules can be connected and AD through the AD converter,you can get a more accurate value of soil moisture ;
