In the first post of this series, we built a simple prototype project using an Arduino board. This second stage involves constructing a full-featured device that can display the current temperature and pressure with an atmospheric pressure chart, and can run off a single battery for several weeks. The source code is available on GitHub, and readers can follow along with the text in this post commit-by-commit.
