“With recent wildfires in California, the outdoor air quality here is changing very quickly*. I created a simple Raspberry Pi station that allows you to watch the PM levels in real time in your browser. With the Raspberry Pi W, you can easily build the station under 30USD. It’s obviously pretty barebones. The goal was for it to be quick to re-create, and for the code to be easily readable rather than to have a ton of features :)
HW Setup
All you need is:
Raspberry Pi (pretty much any model)
PMS7003 sensor
3 jumper wires”
