“Minimal” Arduino/XBee/Pachube Sensor Network

One or two people have asked in online forums for code from my sensor network, and while I’m usually happy to share, it’s full of a lot of extraneous stuff (RTCs, NTP, displays, thermocouples) that might not be of interest to everyone, but more importantly, that probably only obscures the fundamentals of XBee networking and communicating with Pachube.

So with that in mind, I cut out the extraneous stuff, and just left the bare essentials: A remote sensor unit which transmits a single reading from a photocell to a base unit which connects to the internet and forwards the data on to Pachube.
