RE: Ultrasonic range finder - BULK BUY?

[ian.bird@xxxxxxxxxxxxxx]

TBH I really don't know.  If there was a drop it is likely it would
be=20
proportional but it may be a trial and error type of fitment. Could always=
=20
try the analogue route and if it was not satisfactory then explore=20
something along the serial lines. It could be made to work one way or=20
another. There is always the 1 wire ADC unts too as an option.

Thanks Ian/Frank.

HV does indeed have analogue inputs - not sure if I've already used them=20
though, need to check!

That would be the simplest option with no other electronics needed (unless=
=20
I'm wrong?). The question is though - would running the output through=20
Cat5 to Node0 (would be approx 30m max) cause a problem due to voltage=20
drop etc?

Paul.
