I got this one https://www.co2meter.com/collections/desktop/products/co2min... from Amazon, slightly cheaper than the manufacturer's site. It only measures CO2 and temperature, but it has a usb connection and there's actually several Python libraries https://github.com/vfilimonov/co2meter https://github.com/heinemml/CO2Meter If you want other measurements, e.g. pm25, it looks like they have sensors for that but I don't know if you can grab the data from them

I'm running standard Raspbian on the Raspberry Pi. I modified some sample Python code I found here: https://github.com/vfilimonov/co2meter It turned out to be quite straightforward

Did you search for... "co2 meter python"? The pypi package called "CO2meter" (https://github.com/vfilimonov/co2meter) not only works well as a library on Mac OS, but also comes with a web-based dashboard: $ pip install CO2meter flask pandas ... $ co2meter_server Edit: link

The "TFA Dostmann AirCO2ntrol" devices are popular in Germany. Searching for "co2 meter" on Amazon.com one of the top results is an identical looking device. It measures with an infrared spectroscopy-based sensor, which should be quite accurate. There are a few good software packages for recording data, e.g. https://github.com/vfilimonov/co2meter.
