Can someone explain the basics of a hall effec sensor to me? I
believe if I understand correctly that they sense changes in magnetic
fields. Is that correct? If so are they sensitive enough to sense
the magnetic field that is produced by a wire that has been
energized. If not what sensor should I use for this type of
application. I am wanting to sense when a spark plug wire on a small
engine is firing and then send that back to a F-V for a read-out.
Thanks
