+###Arduino library
+Ingo Fischer has written an Arduino library for the sensor, it has a couple of ready made examples: https://github.com/Apollon77/I2CSoilMoistureSensor 
+
+Below are old examples for bare-bones Arduino illustrating a basic I2C use.

 ###Arduino example
 ```arduino
 #include <Wire.h>
