Very interesting!

I’m comparing one SDS011 with an Ecowitt ([link](https://forum.sensor.community/t/a-little-compare-with-other-sensors/1286)) and the result is an average difference of 52%. But I do not have a certain reference that allows us to understand if WH41 overestimates or SDS underestimates.  
You have been able to adjust one to their own average.

Maybe i need to add more SDS011 sensors to not suffer the potential error of a single (maybe i have the worst and i don’t know) 🙄
