Cool. I think the units are wrong though. Their "V" does not seem to be voltage, but rather "input from a 10-bit ADC" which can mean a lot of things but probably (5 / 1023) volts. They also mention that the output is linear, but not in actually meaningful distance units, so you should (empirically?) find the scaling factor for converting to your unit of choice.
