In this post, I’ll discuss some hardware and a new build platform that I used to create an indoor/outdoor air quality monitor. This will be a multi-part post because it has several separate pieces of infrastructure.
In the late summer of 2020, wildfires were burning in Oregon. I saw lots of posts on twitter and other social media outlets of people constructing air filters out of box fans and household HVAC filters. I live on the East Coast, so I was not impacted, but I was curious about what the particulate matter content was inside/outside my home.
