Abstract
An apparatus for sensing rotation of a wheel includes a sensor and a detector. The sensor is disposed in a wheel, and is operable to detect the earth magnetic field. The detector is operable to detect a change of a sensed earth magnetic field in order to sense rotation of the wheel based on the detected change.
