Adding a Carbon monoxide (CO) sensor would be a great add-on to this project in a future hardware release!
Or consider a add-on kit that can be user installed in existing devices…

Hi @trlafleur! Thank you for the request. This is well noted. If anyone else in the community has a similar request, please let us know here.
I’m also interested in a carbon monoxide sensor.

I would rather see a size reduction in the new version. The AirGradient feels a bit bulky, or perhaps the display is just too small. I hadn’t noticed it before, but compared to the new IKEA sensor, it lacks sleekness. The ability to wall mount is great, but also on the wall, next to light switch it looks odd. Otherwise I’m big fan of it.
I disagree with adding this feature, and I agree with the commenter arguing for a size reduction/more elegant form factor.
For the people who want CO, what is the purpose? It isn’t commonly considered air pollution in the large-area environmental sense. It is considered a dangerous and potentially lethal gas that can build inside enclosed spaces due to combustion. For the latter, there are numerous, cheap CO detector/alarms available. Adding this to air gradient runs up the BOM (and price) without any relationship to what it is really supposed to measure.
It also isn’t actionable in the way that PM is (by a air purifier). For CO, remove yourself from the environment/go outside, and ventilate/eliminate combustion source or exhaust leak.
This request isn’t really any different than radon detector to air gradient. Indoor air problem only, also with many commercially available, cheap tests and detectors.
Typical outdoor air pollutants measured by governments/environmental entities:
PM
O3
Benzene
Nox
Sox
The problem with everything below PM is doing it reliably is vastly more expensive than measuring PM. If air gradient can figure that out, now that would be a win.
Adding CO also carries the risk that someone starts relying on it for safety, which this product is not intended for.
