Dust detector

Bought this to monitor local smoke issues from neighbours wood fireplaces.
It does a lot for a simple unit. Easy to use, easy to read. Arrived in good time to Australia.
The numbers go up and down so it must be working.
Have not had a smoky day or night so I can’t say how well the particle meter works for smoke.
I don’t often give reviews unless I’m pleased with the item.
