1.Sensor is for detecting moisture in soil
2.The blue potentiometer adjusts the threshold for soil moisture , clockwise=higher humidity, anticlockwise=lower
3.Digital outputs D0 can be directly connected with the microcontroller through the microcontroller to detect high and low , thereby detecting soil moisture
4.AO analog output modules can be connected and AD through the AD converter , you can get a more accurate value of soil moisture
