With the PyPortal air quality display stuck to your fridge, you can keep track of the quality of the air you breathe.

Using CircuitPython, this project queries the AirNow site API to find out the current air quality index for your location and displays it along with an informative color.

3D printed case and magnetic backing allow you to mount it to your fridge or other ferrous metal surface.

Note that the Air Quality information used in this tutorial is from https://airnow.gov/ which only provides information for the United States and then only certain geographic areas (by postal Zip Code). If you wish to use this project in other areas, you may have to adapt the project to another data source which is not covered in this guide.
