Well, it turns out cheap(ish), low powered and rugged mobile air quality sensors are not as readily available as I first, naively, first thought.
It seems Pimoroni’s Enviro+ Raspberry Pi add-on is a good solution, costing less than $100 for the unit. This has been suggested to me by quite a few people that read the original blog post linked above.
A ‘dream’ device for us would capture carbon dioxide (CO2), carbon monoxide (CO), nitric oxide (NO), nitrogen dioxide (NO2), ozone (O3), and particulate matter (PM2.5).
I’ve bought an Enviro+ to start testing (I’m aware it does not capture all of the above) and therefore want to make sure I’m not missing other, potentially better suited, alternatives.
Thanks for your help!
