The hardware is limited to 31.5' (~ 10 meters). The limitation is on the
design of the receive amplifier's gain module (and noise floor). Generally
scaling this to an integer of 32767 results in a precision of just over 1
tenth of an inch (or 1/3 mm). Few robot projects can maneuver either
themselves or an end effector to this tolerance. Thus the size of integers
is usually not a limiting factor in using these devices.

| Hi I've a Polaroid Sonar Ranging Modul. The longest distance I can mesaure is about 2,7 meters. In my opinion it's not the hardware, but as the result is an integer, so it can't be greater than 32768. Right? Has anybody developed another programm, (...)
