Feel free to put any notes, ideas, etc. here.
Andy — From the schematics, it looks like the TelosB nodes may have a few (six) ADC ports free. If so, and they're accessible, we could possible add additional sensors, if the on-board ones don't suit our needs. Of course, we'd have to buy them ourselves, and this is all predicated on the assumption that there are pins for them, rather than just headers (Dr. Li probably wouldn't like us soldering things to his boards).
Also, the schematic indicates that the nodes have both light and IR sensors, which is a bit more useful, I guess.
