Building a CO₂ Monitor with Python on a Raspberry Pi ...

Making it work on a Raspberry Pi. My ultimate goal was to make a liveplot that people can check throughout the day to see the CO 2 concentration over time, making it easier to spot when the air is getting stuffy. That means I can’t just attach the meter to my laptop while I’m around RC, it needs to be running 24 hours a day in some out-of ...
