Can anyone recommend a reliable, self calibrating CO2 sensors that could be used with raspberry pi and similar or that could transmit data via BLE or wifi?

- scaphandre 7y agoThe '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-Smartphone/dp/B0095HVAKS https://www.amazon.com/Netatmo-Weather-Station-for-Smartphon...
