I spent quite a bit of today getting my tiny air quality sensor working. I’ve ported the code for the full fat sensor over, so that it has full MQTT setting control and all the other trimmings. It seems to work OK. I’ve mounted the pixel ring up against the 3D printed case and the result is rather impressive, and really hard to photograph.
The biggest problem that I have is that my “artistic” back, which contains programatically generated vent holes, doesn’t seem to let in enough air (or the air inside just circulates). I’m going to have to re-design that part. I’m toying with adding a little fan to get some forced ventilation. I’ll put all the code and the hardware design files on Github when they’re finished.
