Chris,
Been there, seen it, got it ;o)
This is what I am using to monitor the level of my water butt
(eventually I plan to automate the filter on the drain pipe to turn on
and off depending on level in the butt). The Sonic sensor ranges from
6" to 255" inches with a voltage step for each inch. I feed this
into a
Idratek QAI (slightly customised by the guys before dispatched to go
from 0 to 3V instead of the normal 0 to 5v) and it can then be scaled
in Cortex.
Paul
