Air quality

It'd be cool to have some PM2.5 air quality sensors in or around the house, especially during fire season. Every year I poke at commercially available products, but always want (a) something that I can grab data from easily over the network, but (b) something that doesn't phone home or only phones home to something I trust—effectively nothing.

I have a personal Pullman air quality site up that reads the latest data from one of the nearby public air quality sensors. Anything I do with DIY sensors could be added to that page.

DIY Possibilities

• AirGradient DIY Air Quality Sensor
• CanAirIO
• Build a low cost air quality sensor with CanAirIO

Inspiration

It'd be cool if a final answer did something close to these but without relying on a central service or proprietary nonsense.
