What type of sensor needed to indicate plumb?
I know nothing about any of the angular sensors that Parallax sells. If I wanted to attach something to a pole to measure (indicate) whether a pole's vertical level position is leaning too far left or right and too far to and fro would I use this one - http://www.parallax.com/Store/Sensors/AccelerationTilt/tabid/172/CategoryID/47/List/0/SortField/0/Level/a/ProductID/93/Default.aspx ?

Another way is to use mercury switches.

Two potentiometers with pendulums as shown in the attached diagram would work. If greater accuracy is required 4 pots wired as 2 Wheatstone bridges would provide greater accuracy.
(Well actually that's a bit flippant, in windy conditions a plumb-bob is not the right solution!)
Actually, if you mounted the plumb bob inside a length of pvc pipe it would not be affected by wind and could provide a reasonably accurate plumb indication.
