  This is the last follow-up of the tutorials:

  • M5Stack: Fresh air checker helps you to stay safe from #COVID-19 and,
  • Nginx: Docker, Flask and Let's Encrypt (SSL),

  in which I explained how to build a CO2 measuring device using a M5Stack and an SG30 sensor, send the data to GCP, and offer it using HTTPS.

  Fig. 1: CO2 reporting widgets on Android and iOS.

  These sensors can help to prevent Covid-19 spread in a room. If you want to implement the complete pipeline, check out the links above. This tutorial connects the data to your Android or iOS phone to see that in a Widget (see Fig. ...
