A device like that would be interesting to have in a lot of places.  Like
measuring current to fuel pumps as a take on their state of repair.  Wouldn't
it be nice to have several of these and other sensors working in "background"
on another "page" of my engine monitor that I could peek at from time to time.
Ain't technology wonnerful ... Jim S.
