A very common way of measuring traffic volumes is via bluetooth MAC address broadcasts. The Wisconsin DOT even makes the traffic counts derived from this data interactive and public: https://wisdot.maps.arcgis.com/apps/webappviewer/index.html?...

This would equate to forest management practices, not logging. They likely chipped or burned the underbrush and low branches after removing them from the forest, which wouldn't be a profitable business practice.

PLA Filament (The most common type in personal 3d printing) is technically compostable, but realistically will likely end up in a landfill due to inadequate disposal practices in most waste management systems.

Thanks! Last I checked they were no longer selling version 1 of this product and hadn't released version 2 yet. This might fit the bill.

I have mine on a homekit enabled outlet ($20) for scheduling and presence-based triggers. Unfortunately I haven't found a homekit enabled air quality sensor to pair with it.

With the recent California fires, I've been looking for a decent option. Unfortunately the Elgato Eve sensor is no longer sold, and the few other consumer products still hover in the $100+ range with poor reviews.

PurpleAir sells an indoor sensor, but it appears to be limited release and somewhat 3D printed. https://www.purpleair.com/

I would guess that it works similar to a water pump- pushing is always more powerful than sucking - but check this out for some detailed analysis (and more data on DIY air filters) https://smartairfilters.com/en/blog/where-should-an-air-filt...
