    How to tell original from fake DS18B20 temperature sensors.

    • I have recently purchased Sonoff DS18B20 temperature sensor. I was curious to check if it uses an original temperature sensor. For this I have tried this Arduino sketch: https://github.com/cpetrich/counterfeit_DS18B20 . To my big surprise it turned out that it has a counterfeit sensor. Could anyone test it as well and confirm or deny my findings?
