I've been setting up PM sensors in my home since installing a log-burning stove last winter; I've found a couple of interesting things thus far; Notably, despite the FUD, air quality _in_ my home isn't affected by it.

What does affect air quality in my home massively, are the people parking their vehicles surrounding my home morning and afternoon as they drop off and pick up their children from the nearby school. I see a 10x ambient measure at these times. I was starting to think about how I could use BLE monitoring to track this somehow (the other thing my home is surrounded with at these times is devices broadcasting Bluetooth "beacons"(?)); could be an interesting experiment.

The next step for me is really knowing what and how something can be done about the pollution (generally speaking); Monitoring is great, but what's the next step?

"Monitoring is great, but what's the next step?"

Short term: install air filters

Long term: banning ICE cars

Long term: move to a different home

Well, I did. But not everyone can. And long term it would be nice, if the cities would have breathable air again.

Also where there is good air, there ain't so many people.

Longer term: move to a different planet.
