    Hi, radhoo. There’s any chance adding a microSDHC slot and make this a fully portable unit?

    Hi nox .

    Yes, although I’m not sure which one is going to have it first , model C (no pollution sensors but with GPS), or an model D update.

    But model D already has a generous separate EEPROM memory added there to store data while unit is offline.

    Very nice development. I was wondering if the hard/software is Opensource.
    For the PM2.5 sensor a PPD42 with fan seems to result in much more accurate reading. http://indiaairquality.com/

    Thanks Rob, yes, model D is open source.

    Do you have any suggestions on VOC sensors alternatives?

    For VOC did you look at the MQ135?

    I looked at Github, but I could only find the MicroGeiger source code. You have for Uradmonitor-D also a Github Repo online?
