Yes, that’s pretty appealing (& motivating)
Yes I did a tiny bit of microcontroller stuff many years ago & always wanted to get back to something in the ballpark.
That’s permissible! Anyway thanks, sounds like it will provide a worthy use for my sadly underworked raspberry pi.
Sweet! Looking forward to read this and learn some new tricks from the Nerves pros 
BTW, Nerves is one of the technologies I had more fun with in the last years (on top of some good profit). I am so thankful to the maintainers!
just had a second look. some thoughts:
The last points only make sense if enough people really build the station and are interested. But making this into a really usable project it would be a great opportunity for nerves/elixir to gain traction in the maker scene.
I don’t think you’ll learn anything new about nerves from this book. It is a great first project, but does not seem to dig too deep. But its not finished yet and I did not look too close, so please correct me if I’m wrong.
I can see CO2 reading being useful if the device is in a farming/gardening environment for example.
That’s what I have in mind with this project. I’ve looked the hardware up and I’ll probably pull the trigger.
I’m not sure if something like that is what they had in mind with that sensor though.
Got the book using the discount and started reading it. You’re right in that it’s a beginner resource. That’s good in general because it fills a niche: I am sure there are many people that would love to get started with Nerves with a cool project, and this is a good book for that purpose.
As for me, I am crossing fingers that the authors will consider writing an advanced Nerves book, to really tap into their expertise Still enjoying browsing through the book though.
