With spring fast approaching, I'm currently working on getting this all up and running.
Most of the sensors are done and currently outputting data to a basic web page and the code for posting data to the database is done. Over the next few days i'll be working on setting up the Arduino to start posting the data to MySQL and from there it'll be possible to graph all the sensors and setup alerts.
Some of the Arduino code is now available on GitHub.
