This looks great! Thanks for sharing it!
It's really nice to see an Espruino project using LoRaWan too. What's the chip/module you're using for it?
Also just so you know the hackster article links to:
https://oshwlab.com/gendor/air-quality-monitor.(which is 404 - you have to manually remove the dot!).
It's a shame you had trouble with the MDBT42Q though - they can be a bit fiddly :(
I originally used the RN2483 module, but when that became unobtainium I switched to the LoRa-E5 (now called Wio-E5) module from Seeed. It has a STM32WL SoC, which contains both an ARM Cortex M4 and a SX126x LoRa radio. The ARM Cortex M4 runs the LoRaWAN stack, and uses an AT command set.
Thanks, I've now updated the link!
Thanks! I don't know if you ever did a module for communicating with the Wio-E5 ? If you did, it'd be great if you could contribute it to EspruinoDocs so others could use it...
I want to do that, but need to find the time to separate out the LoRa code into its own module. I also wrote a CayenneLPP encoder that I'd like to contribute as well, but again need to find the time to actually put it into a module.
I contributed a module for the MAX1704x Battery Fuel Gauge a while ago, but I'm not seeing it when I use the search function on the Espruino website?

Thanks - it is there... http://www.espruino.com/MAX1704x
Maybe the file containing the search keywords for it got cached by your browser so it didn't show up? It can also take me a week or so sometimes to merge and then push the changes to espruino.com
It showing up for me now in the search function as well, thanks for checking!
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.
