The pins are already mentioned on the backside of the module. It contains 4 pins and a potentiometer.

Interface the sensor with any microcontroller using the Analog-to-Digital converter (ADC) Pin or A0, or connect the digital pin (D0) of the sensor to any digital pin of a microcontroller.

The threshold for digital pin can be set by using potentiometer available in the module.

 

Connections using Analog Pin A0:

Pins on Soil Moisture Module Arduino UNO/ Mega
