Hi all,
I've been working on an open-source outdoor air quality monitor using Espruino for a while now, and it's finally at a stage where I feel comfortable sharing it with you folks! The first batch of ten prototypes used MDBT42Q modules I bought from Gordon, but I found them really hard to solder (even when using a hotplate), so I've since switched to using the E73-2G4M04S1B, which is a bit larger.
Details about the project and build instructions is over on https://www.hackster.io/gerrit-niezen/openairmonitor-494b2c
If you'd like to know more about the story behind the project, have a look at my blog: https://gerritniezen.com/designing-an-open-source-air-quality-monitor-and-building-a-community-sensor
Please let me know if there's anything else you'd like to know, and if you'd like to be a beta tester.
Cheers,
Gerrit
