Your post has made me consider getting a C02 monitor, will something as simple as this 20 buck Chinese version suffice? https://www.newegg.com/Product/Product.aspx?Item=9SIADJN8NP4860-9SIADJN8NP4860&gclid=CjwKCAjw_MnmBRAoEiwAPRRWW1Dv2zvRP-y-ajNDezjPEmJ0RMZDDzJpZRj0kpjceEO3CeQm0yIwqRoCW18QAvD_BwE&gclsrc=aw.ds https://www.newegg.com/Product/Product.aspx?Item=9SIADJN8NP4... Seems a useful thing to have. Separately it is very stressful being on stage at conferences that are stuffy with no fresh air, hot stage lights and probably very low oxygen. I had a friend who did press ups before going on stage to energize herself as the tech conference chair and raise the energy level of the sleepy audience - she got really out of breath!

IIRC the thing to be aware of is that a monitor that actually measures CO2 is going to cost several hundred dollars. The cheap ones don't measure CO2, but some kind of VOC as a proxy. So depending on the source of the CO2, they can be more or less accurate. Something to research. I'm not an expert, just someone who recently did some shopping for CO2 monitors for my home.

  What did you end up buying?

    I didn't. Part of my requirements are that I can tie the device into my home automation. After doing a lot of digging and not finding something I wanted, I shelved the idea of adding CO2 sensors to my house for now. Decided instead to just assume CO2 was high, and I'm having a whole-house HRV installed in a few months.

I can't see that link (it says the product ID is invalid), but I know that measuring CO2 is actually pretty hard and requires some somewhat expensive stuff, but measuring things like O2 is easy (i believe, i'm going from memory here). So most cheap CO2 monitors are actually just oxygen monitors that aren't actually measuring the CO2 levels but are measuring the drop in O2 levels and extrapolating from there. I don't know if that matters for what you might want to use them for, but it's something to be aware of. I don't have mine any more, I actually borrowed it from a friend and it was a fairly expensive one (like in the $200 range) that he was using for some other stuff.
