| (...) The device operates at 40kHz, the transmit and receive piezo devices are only resonant at that frequency. Even though the measurement period is short (time from transmit to time to receive) it is necessary to wait quite a while for the sound (...) (19 years ago, 21-May-06, to lugnet.robotics)

| (...) Wow! That's a lot lower than I'd have expected - at that frequency there is a good risk of harmonics from normal sound interfering with it. (...) Right - 350 meters per second is pretty slow by computer standards. (...) (Not to mention things (...) (19 years ago, 21-May-06, to lugnet.robotics)
