The code, as it is, uses several feeds in a single feed group that you'll need to set up first.

If you don't have an Adafruit IO account or are unfamiliar with setting up feed/groups, see the Welcome to Adafruit IO guide.

You will need to set up a group named Environmental_Sensor containing the following feeds:

  • 03um
  • 05um
  • 10um
  • 25um
  • 50um
  • 100um
  • pm10_env
  • pm25_env
  • pm100_env
  • pm10_std
  • pm25_std
  • pressure
  • temperature
  • humidity

Add your Adafruit IO account credentials to the file and it should be ready to go.

You can look at the collected data directly in the feeds, but making a dashboard gives a better (sometimes) view of it.
