Bill, I would like to see an implementation of a particle counter. This might be a good counterpart to the proposed and accepted "air quality monitor" for gases. I'm a woodworker and live out west, where wildfire smoke particles, and woodworking particles often cause a lung hazard. I'd like to implement a small, self-contained arduino-based measurement device with a small display, that could be placed in the house or shop. There seem to be a couple sensors, including one by Shinyei PPD42NS, and an Omron B5W-LDo1o1-1 that are under $20. Commercial particle/dust sensors run $300-$10,000.

I like this idea, the issue I have right now is simply getting my hands upon one of these sensors. Perhaps I was too hasty in rejecting Seeed Studios offer to send me free stuff!
The Omron B5W-LDo1o1-1 is currently out of stock at DigiKey, but I will keep my eyes open.
Right now, due to the COVID-19 situation, I can only purchase items from Canadian vendors. Orders from outside Canada often arrive with duty fees to be paid and during the crisis, the couriers won't collect them at the door anymore, you need to go to a depot and pick them up. Currently, I cannot leave my home to do that.
I'm going to ACCEPT this but will leave it here for a while in hopes someone can suggest an alternate sensor or one that I can obtain from a Canadian vendor. Thanks for suggesting it!

There also seems to be an Amphenol sensor of similar performance with decent documentation; the SM-PWM-01C. This part is available when I search Digikey, but perhaps that's not the case within Canada. Thanks for your attention on this!
