I have two different air quality monitors now (QingPing for home, Aranet for the road) and the CO2 readings tend to diverge, sometimes a lot. Why… is this, as in technical details?
@astrokatie.com @kateviolette.com this seems like the kind of thing you might know

possibly relevant note: the QingPing has never been calibrated manually and I may or may not have done that with the Aranet at some point a long time ago

FWIW last year I bought 4 Aranets for an event and they differed in a range of up to 60ppm before I calibrated them all... Then they were generally 15ppm or less apart.

I haven't looked at the technical docs for these yet but CO2 detection often uses an infrared component and localized heat sources can skew the readings (sunlight, near a cooktop, body heat, near a heat vent etc).

I have a pocket CO2 monitor that needs to be calibrated something ridiculous ike once a week. It tries to recalibtate itaelf, and sknce it's never outdoors, it loses track of what normal is

Maybe you've already done this, but I know for the Aranet, it can use recalibration every once in a while (like on the order of 6-12 months if I recall correctly from the manual). I'm less familiar with the QingPing but I wouldn't be surprised if it also could use recalibration sometimes.
