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.
