Working as described

I received my sensors yesterday, took one out of the bag and hooked it to a Raspberry Pi 4. It's working exactly as it should and I was able to get it running easily.
Caveats on setting these up: 1) I think they use a significant amount of current, you may want to power the SR-04 separately from the Raspberry Pi power pins
2) the echo pin of the SR-04 produces a 5V pulse, so you'll need to set up a simple voltage divider to provide a 3V input to the Raspberry Pi.
3) One more reason to use Python 3 - time.perf_counter() will improve the precision of your pulse measurements!

I think you'll be happy with these, have fun!
