I see the aliexpress link to the PM sensor doesn't work (at least not in the US); where else do you recommend buying one?

Yes, sometimes some components are not available for all countries. Just search for the same sensor on aliexpress. There are many vendors for the same sensor. Some will ship to the US.

Search for SDS011 on aliexpress, the USB version. It's good and not too expensive.
