I've been wanting a CO2 monitor for a long time. (As a virus monitoring proxy: my heart condition is most like a result of #COVID, and I'm fairly anxious to avoid getting it again.)
I finally got around to ordering a sensor (SCD40) plus some CircuitPython microcontrollers, and got a basic monitor up and running in a few hours. Fun! Now I just have to build some sort of case to make it easier to carry around.
