CO2 levels

This dashboard shows the latest readings of the CO2 sensor in my office. I'm using a Aranet4 and my Raspberry Pi is reading the data on a 1 minute interval via Bluetooth. I also wrote a blog post about it. Should the levels rise above the recommended threshold of 1000 ppm, don't hesitate to reach out to me on Twitter or Mastodon to remind me to ventilate!
