all_in_one (and combined) needs to recalculate humidity based on compensated temperature

Open doctorkb opened this issue 2 years ago • 2 comments

This applies to anything using the relative humidity (RH) and depending on a compensated temperature.

The RH needs to be converted to dewpoint with the raw temperature, then converted back to RH using the compensated temperature. Taking the RH as-is results in a lower-than-accurate humidity.

It’s solved in this code

Yes, and I have my own solution for it also. But it should be in these main libraries' examples, in part because a lot of folks don't understand the relationship between temp and RH.

I guess you referred to this code:
