I’ll have to reach out to their team, but at the moment the Bill of Materials doesn’t appear to list an Air Quality sensor at all. So that’s confusing. I was interested because I’ve been wanted to measure VOCs in a manufacturing lab but that tech is still expensive.

In the US West, people check on the AQI all the time when there are forest fires. Kids get kept inside at recess, old folks are told not to go out, sporting events get cancelled.
Now that everyone has masks sitting around I see a lot more people mask up when it’s smoky.

The Purple II achieved excellent results in AQMD's most recent testing. The PM10 score was not quite as good, but it still seemed to be the best PM2.5 sensor in the price range.
I have yet to find any gas sensors that weren't utter trash or cost thousands. I wonder how good this MIT built tool's NO2 sensor is.

My exact thought as well.

Because the numbers help us diagnose and address problems with our air more effectively than not having them. It also gives something for people to act on, especially the ones who don’t believe they’re affected by the issue.

You can't advocate to have a problem fixed if you don't know it's a problem in the first place

Why do people need to check the air quality? Like what do you do if it’s poor? Not go outside?
I just fail to see why people want this, it’s not like I can adjust my day based on the quality of the air around me.

Refurb prices on Apple's store seem high compared with other refurb sellers. Have a family member upgrading from old iphone (7 or 6, so no longer secure), and they are interested in potentially getting the 15 when it comes out and selling the phone they buy now - would you recommend they buy a 13, 13 Pro, 12 or 12 Pro now?

Lets just over exaggerate the overall emmissions by placing the sensors on top of a car? Great idea team. Next time lets just place them next to an active volcano or better yet lets just place it on a co2 effluent pipeline at breast level. Same way the professionals do it to measure global CO2 ofcourse.

Have a family member upgrading from an old iPhone. Do you recommend getting the 12 or 12 Pro? How do you like the camera on your 12?

In the handbook for assembling, they're using a sensirion sensor (probably sps30) for particulate measurement and some unspecified "gas probes".
They're whole setup looks somehow more complicated than necessary. Would've been much easier with an ESP32 or Arduino board...
Unrelated, for VOCs measurement, Bosch has two sensors BME680 and BME688, which together with their proprietary algorithms (BSEC) and the BME AI studio, can be used for VOC measurement.
