The CO2 sensor would be a nice addition to my project. Do you have experience with the MH-Z19B, is it accurate enough for indoor use?

I've only used it briefly, but I have also seen it used in DIY building management projects. The biggest issue I saw with it was power consumption: up to 150mA @5V is 0.75W, and I think it can take a bit of time to 'warm up' so you can't just turn it on for a few milliseconds every hour. But that should be fine if it's plugged into the wall.

It's also fairly expensive, on the order of $10 rather than $1 last I checked.
