Hell yea! 
I mean, there is logic behind both Celsius and the metric system! But there is always some reactionary countries: āU.S. remains the only industrialised country that has not fully adopted the metric system as its official system of measurementā. If you could start using it in movies, TV shows, and by NFL commentators I would be happy. F - 32 / 1.8 isnāt always easy to do in the head 
BTW: Anders Celsius was a 
Nuff with the off topicā¦ Iām not sure if I would call it a general misunderstanding, but many (not just in this forum) doesnāt seem to understand that those sensors works differently. Perhaps not technically correct per se, but I think the easiest way to explain it is that:
- DHT22 sends data to the MCU
- MCU reads data from the DS18B20
Or MCU sends āgimme some dataā to DHT22 and the DHT22 sends it back.
MCU tells DS18 to start measure temperature, do a analogue-to-digital conversion, store the value in your scratchpad memory and Iāll read it when your done. If I donāt have timing issues, Iāll sit and wait for you to finish, otherwise Iāll come back at a later time (hence the option to change setWaitForConversion()).
