Outdoor air quality sensor.. hardware, config, etc. questions

Alright, so I've got a creative coding project I've been running for months now that relies on hourly air quality measurements locally.

The first local sensor went down a couple weeks ago, so I switched to a new on that popped up shortly after.. And now that one has been down for days as well.

This is actually a really bad time for it to go down; our local air quality has been absolute garbage for a couple weeks now, frequently above 200; I just went out this morning to take out the garbage and came back inside hacking and coughing (I've got severe allergies and asthma). Plus, I want to collect a year's worth of data so I can create some visualizations with it.

I've done some cursory looks at DIY AQI sensors, but none really look to fit the bill for what I need.. And there are some you can get off the shelf, but then I've got to wonder about power and everything else needed (plus where to mount it). Has anybody else set up an outdoor AQI sensor before? Definitely want some other opinions before I start thinking about dropping that kinda money.

Ideally I'd also set it up to report to WAQI so I don't have to change the code for my project and make it available for other folks to use.

Haven’t installed the outdoor unit yet, plan to via power over ethernet, but happy with indoor so far.
Yeah, that's one I looked at, but wasn't sure about running power to it, and also not super impressed with the operating temp range (just -4F degrees at the bottom, which makes me wonder what happens when it exceeds that).

Maybe nothing...this probably just means that the parts used to build it aren't rated for low(er) temperatures.

But it probably won't be as robust, because manufacturers don't do stuff that makes things more temperature tolerant for free when they could charge for it.

So basically...you're adding risk.
