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:
Though with your steps it at least starts, but the webserver fails, and CTRL+C doesn't work ^^
* Serving Flask app "co2meter.server" (lazy loading)

Use a production WSGI server instead.

co2meter_server writes measurements to "logs/co2.csv" in the current working directory every 30 seconds or so. As long as there is no measurement, you'll get this error from the web app trying to access the file. Just wait a minute and refresh the page.
