Portability is a nice feature -- could see using that when out for a run or a bike ride.  Does the Atmotube collect data continuously, or only when you run a reading?

Continuously until you tell it to stop - the documentation says up to 10 hours.  I'm a long-time runner and have carried all kinds of devices with me when I am out.  I don't think there would be an easy way to carry it since it has an internal fan that runs when it is taking the readings.  You would have to get creative.  Here in Minnesota the outdoor air is not a big concern but the indoor air quality is of interest as we spend a majority of time indoors during the winter months.

Great point. I got the PurpleAir because it has been rated most accurate against benchmark devices. I guess one has to weigh that against the problem that PurpleAir has fewer home automation options compared to something like Foobot, for instance.

Unfortunately, it looks like there is no longer a PurpleAir IFTTT channel. Maybe they took it down?  There is a driver for Home Assistant, although I'm not sure how I would link that to C4.  

 I figured integration would be easier to solve than device accuracy, but maybe they are both hard to solve!

 

I used the study linked above when looking for an indoor air quality monitor about a month ago focusing on the Field R squared numbers.  I didn't consider the sensors that cost thousands of dollars as they were out of my price range. Based on this chart http://www.aqmd.gov/aq-spec/evaluations/summary-pm I narrowed it down to the Atmotube Pro, Kaiterra Laser 2+ Egg and PurpleAir PA-I-Indoor.  I chose the Atmotube Pro - since it is built as a portable device (comes with a carabiner) and had good R Squared numbers for PM1.0 and PM2.5.  The app is excellent and gives me a notification about once a week to run a reading so that I have an ongoing chart of the air quality measures.  I don't know what the market size is for any of these air quality devices but I would think at some point they are going to become more commonplace in homes.

Used Neil to update my system to 2.10.5.  Couldn't be happier with the process and results - definitely recommend!
