Citizen sensing with Arduino

In 2013 I did a summer project on using the Arduino as a platform for "citizen sensing". This rapidly became an exploration of how to create hardware and software that can do sensing while operating in a very low-power regime, such as one would need for an environmental sensor.

There were several results from this project -- one of which wasn't an actual solution to the motivating problem I'd come up with. However, it did generate a lot of notes about low-power Arduino programming, both for hardware and software, and a software library that embodies some of them

Below are some notes I made as the project went along.
