Air quality is a big concern. We take the air that we breathe for granted, and sometimes that air is full of pollution. Forest fires in Canada and hill fires in the United Kingdom are all recent examples of fire polluting our air, so how can we check that it is safe to go out?
In this how to we’ll build a project that uses air quality data from the OpenWeather API to give us an indication of air quality before we leave home. The data is visualized using a Raspberry Pi Pico W, a $6 microcontroller that can go online, get the data and then display the data using a strip of NeoPixel RGB LEDs.
