Fenceport error...? How many fencepost will you have on a 10 meter
fence, if you have one post every meter? (The answer is probably 9 or
11, and most likely not 10.)
So unless you actually need 5 seconds to refresh the sensor, you'll have
the answer right away, even though the next sensor won't be scanned
until 5 seconds later, so I suspect 150 seconds wasn't that bad an
answer. :-)
