Abstract
An AMR gear tooth rotation sensor and a method for utilizing it are disclosed. These facilitate easy manufacture of the device without sacrificing either high sensitivity or high signal output. This is achieved by forming individual sensing elements out of AMR stripes and then connecting four such sensing elements as a Wheatstone bridge. The latter is attached to a permanent magnet that provides a bias field whose value rises and falls as wheel teeth and valleys (respectively) move past the rotation sensor.
