With how bad air quality has been this year, I grabbed myself a DIY AirGradient kit so I can monitor air quality in my living space. It was easy to assemble and only required a little bit of soldering knowledge. I’m definitely not proficient enough at soldering as many components ended up crooked on the board. Still works though lol.
In the picture it’s running ESPHome with the configuration from ajfriesen on GitHub.
This is really neat! How much did everything cost in the end, and are you going to get some kind of case for it?
