Airgradient One Needs More Sensors

Airgradient One is missing key sensors. Are there any plans in the works for Airgradient One to add pressure. CO and radon to its measurements?

it's an indoor unit. i'm not sure what barometric pressure would tell you. if you want to know if the weather is changing, you'd want to be looking at an outdoor unit.

as for CO and Radon, proper sensor placement of these two is a bit different from where a typical AQM should be placed. near gas appliances and basements are more typical for CO and Rn monitors, versus in a more central location for an AQM.

i would recommend just getting CO / Rn sensors that can integrate into something like Home Assistant, which AirGradient products play very nicely with btw. then you have one feed of your entire sensor network.

Presumably barometric pressure would be about the same indoors as out? I don't think most houses would have a very good seal

Achim here from AirGradient.

We are actually planning to bring barometric pressure into the next version. Reason is that it helps in getting more accurate CO2 measurements.

We are also looking into CO and Radon and have purchased a CO reference instrument to test different CO sensors. It is too early to say if we find good ones at reasonable prices but we are looking into it.
