Here you'll find plenty of informations about various sensor-types and how to connect them to a midibox. If you're interested in working with sensors, you might also want to check out the ACSensorizer-Midibox project.

Sensor-Wiki maintains a free list of possible sensors you could experiment with : http://www.sensorwiki.org/doku.php/sensors/introduction
