Comment Comment by scaphandre The 'Netatmo' home weather stations record CO2 level. Mine shares over wifi. I get around 400ppm with windows open for a while, or 1200ppm with windows closed.I don't know what the calibration mechanism is, nor the specificity.It's around $100 on Amazon - https://www.amazon.com/Netatmo-Weather-Station-for-Smartphon... parent scaphandre 7 years ago
