Hi! As an Arduino noob, i dont know a lot about the sensors, but still they seem to be very interesting stuff. So maybe you could just [u]name some sensors that you know.[/u] They should be as simple as possible. Just plug in (with some resistors) and ready to go.
Here are mine that i know so far: 1) Light Dependent Resistor (LDR) 2) IR receiver 3) Piezo plate, for knock sensor 4) temperature sensor 5) Microphone 6) PIR motion sensor 7) tilt sensor 9) humidity sensor
