I still can't see how my other point that of self retriggering is addressed.
I imagine the mcu on board the sr04 won't read the trigger pin again until it has finished sending the echo pulse. But that's entirely supposition on my part. If it were re-triggered, you might expect a second echo pulse, which would be ignored by the Arduino because it wasn't expected. If the two pulses were read by the Arduino as one long pulse, this would be noticed and interpreted as an incorrect distance measurement, so i guess that's not happening.
