A early page about the Sonar
The sonar communicates through a standard serial protocol ([https://en.wikipedia.org/wiki/8-N-1 9600/8-N-1]).
Using an Arduino board equipped with an uart port it's possible to test the sonar performance.
The sketch can be found at https://mega.nz/#F!Bo8jHabQ!kwxQR5jFZorFaOLdQKsTdw)
