Fixing up the D1-mini base as we speak.
Which CO2 sensors are you planning to use, btw?
@fribbledom I ordered some HDC1080 CCS811's to start with. They're i2c, and are supposed to be easy to work with. I'm open to hearing about better options.
@fribbledom btw, I found one case of a (faulty?) voltage regulator on a d1 that was running hot enough to throw the temperature off by 10F. Moving the sensor away from the d1 fixed things.
https://github.com/davewsmith/notebooks/blob/master/temperature/MovingTheSensor.ipynb is one of the relevant lab notebooks.
