Put together a DIY air quality monitor! ( beehaw.org )

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.

I’ve been curious about getting a CO2 monitor after I heard that excess CO2 in rooms cause your brain to get dumber. I can’t think of what to call it, maybe the CO2 talking.

(And just to be clear, I’m talking about CO2, not CO, we have a CO alarm.)

I have one of the non DIY kits, they’re pretty cool.

This is really neat! How much did everything cost in the end, and are you going to get some kind of case for it?

total ended up around $85 including shipping.

I’m planning on 3d printing a case.

That noice but I can’t get over then holding it by the USBC connector… how in a right mind would you do that ?

yeah I know it’s not great for the port, but it’s light enough and small enough that it was fine for the photo

Diurnambule ,

I can understand that logically but that strike some thing which forced me react…

yeah it’s running firmware made by the ESPHome integration and is discoverable on homeassistant.

Thats so fucking cool!!!

How does it calibrate?

Fonderthud ,

Not op, I’m not seeing anything about calibration for PM or VOC just stuff for open air bump tests. Interesting alternatives to filter load and PIDs I wonder if they’re robust enough to find their way into EPA or OSHA level investigations, I haven’t run across them yet

Very cool! Do you have more pics video of putting it together?

I unfortunately don’t, but it was basically just soldering everything together on the PCB. AirGradient provides build instructions if you get a kit.
