AirGradient DIY Air Quality Monitor

I saw this air quality sensor on Jeff Geerling‘s YouTube channel at the end of last year and thought it could be a cool project to have a go at.

You can purchase the parts separately from sites like Banggood or AliExpress but I noticed on the AirGradient site they now sell a complete kit so I ordered a couple, the shipping was fairly expensive and took a few weeks but seemed more convenient than sourcing myself. I ordered to the UK from China and didn’t get hit with an import charge.

The instructions on the AirGradient site are pretty clear and Jeff’s video is also great so I recommend following those for instructions. There were a couple Arduino libraries that the guide doesn’t mention, screenshots below:

Assembly was pretty straight forward and with some coaching from my Dad on soldering properly we got there pretty quickly! Thanks Dad!

As it stands I’ve not got the data being forwarded anywhere, it’s just outputting to the screen. Collecting the data is one of the projects I’d like to work on next.
