This sensor is compatible with Arduino if you use our Open-Garden or Open Aquarium board with the Aquaponics/Hydroponics shield. These board include the adaptation circuit of the sensor.

This sensor is only compatible with Waspmote and the Smart Water sensor board. Not with Arduino.

This sensor is compatible with Waspmote v15, we have never integrated it in Arduino.

If so, is there any tutorial ? Can I do it with the same library?
No, we haven't got a tutorial for these sensors for Arduino, also they are not directly compatible because you need the adaptation circuit of each sensor. You will need to use the recommended board for each sensor if you want to use them.
