hmmmm, I guess I am in a code 18 behavior … sorry for washing time to everyone, just see the error my bad

You need to remove the examples from the library examples folders otherwise they get included.


#23

Odd. Does that only happen when compiling in the cloud? (It doesn’t happen when I compile locally.)


#24

Also be aware that most Co2 sensors are designed to have some time exposed to ambient Co2 conditions and many auto calibrate. If you want to have a Co2 sensor in a Co2 boosted environment you need read through the data sheets to see if it’s going to work in your environment. I ended up using the Telaire T6615 but that might be above you budget.

Seems like you have converged but +1 on the SGP30 from me too. Don’t forget to set the baseline by running for a while in clean outdoor air, for example.

I have also had problems with drift with other sensors and from what I can tell the SGP30 is consistent and stable longer term.
