    The vThings don't do CO, but they can do pressure and particulates.

    Does the vThing do RH&T in the same instrument as particulates?

    does just CO₂ by default. You can add temperature & humidity then pressure as one upgrade path (i.e., I don't think you can add just pressure without T&H) and, independently, you can also add a “dust” (PM 2.5 and PM 10) sensor. It gives separate readings for the two particle sizes:


    I got CO₂, temperature, humidity and pressure, but not particulates.

    I don't think he does RH&T + particulates without CO₂.
    thanks guys, thats helpful. I was thinking of a device similar to a heating engineer's flue emission reader device, but that might not be available.
    A bit late to the party, but my colleague has just shown me this:

    Which appears to be a more 'networked' solution, rewarding users for expanding the area monitored etc.

    Also uses 'freevolt' which appears to be wireless charging so a few interesting features. Not sure how accurate & calibrated the whole thing can be though.

    Only does CO and temperature though.
