    Are you installing it in a shelter? Hope you’ll never need it but we live troubled times.

    You’ll need to increase your compensation capacitor. Calculate your cable’s capacitance then add that in the equation posted on the blog. Let me know if you need help.

    Well, indeed, the KIT1 is the starting point here, but you can use its mechanism with any detector you have or build. What this means is that you can look at the way the KIT1 uploads the data (via the EXP protocol) and implement that for your device.

    Let me know if you need any help.

    Well there is a curve that shows resistance to alcohol ppm equivalence here: https://www.uradmonitor.com/metal-oxide-voc-sensors/

    But please understand that VOC means a mixture of substances and you cannot compute a generic VOC ppm due to the unknown nature of this mixture. Best you can do is to estimate carbon concentration or do equivalence to various substances such as alcohol. In my opinion it is not worth it as it doesn’t bring any new information, you’ll see the same graph shape, only the figures will be different as your approximation function will be linear. You already have the “VOC-AQI” for that.

    Connecting to the smoggie can be difficult from some devices. When this happen best thing is to try another phone / laptop / etc.

    The smoggies can also be configured via USB.

    Yes, the smoggie is constantly being improved, more work is being done on the enclosure, please check the website and the FB page , you’ll see some pics on this soon.

    hi Urs, I see the unit went online but is now offline again: https://www.uradmonitor.com/tools/dashboard-04/?open=14000013

    How did you get the Wifi running?

    Do you need any help for getting it back online? The firmware on it is old (v53) and has some known bugs, we should do a firmware update asap!

    Let me know if you have the time,

    Thanks,
    Radu
