This website has extremely helpful tutorials to connect many different sensors on to Arduino boards.

Its bassically prepared for processing rather than PD. However, tutorials on the same operation for PD can be found at another address.

The images shows a ultrasound sensor being connected to Arduino. This sensor emits a pulse wave that "pings" on the input of the software (PD or Processing). The closer a object is from the wave source, the quicker is the "ping"

A simple technique that could have many applications on interactive art works.
