This brand new Learn Guide, Purple Air AQI Display will show you how to build a large LED matrix display to see your Air Quality Index and description at a glance.
The quality of the air we breathe can be very important, particularly right now with recent wildfires on the west coast of the US.
This project shows how to display the Air Quality Index (AQI) of a based on the Purple Air real-time monitoring community’s outdoor sensors sensor right on your own LED Matrix display.
Your readings will be updated automatically over WiFi, and you can plug in the sensor ID of any Purple Air sensor in the world!
We’ll show you how to build this project with either the Matrix Portal or a Metro M4 Express AirLift with RGB Matrix shield.
I created a similar project that uses an Adafruit Huzzah and the powerful Adafruit-GFX-Library:

My focus was on a low power solution (so no shiny LEDs) and aggregation of data from several sensors around my place.
Thanks Adafruit for continuing to bring us so much even during these difficult times!
