@robert-hh said in Wi Py 2.0 Internal Comparator?: DS18B20 Hey Mate, Thank you very much for your reply. I will definitely will give it a go to the DS18B20, it looks way easier to use mate. I do agree that adding external components (resistor, comparator) adds extra burden to the limited power, and that is a killer for me. Cheers ColombiaAustralian
