Abstract
Disclosed ia an apparatus and methodology for detecting tire (1) rotation by associating a piezoelectric sensor (250) with an enclosure housing (210) tire environment related sensors and electronics. The enclosure (210) may be mounted in a tire (1) in a location subject to multi-dimensional strain and a signal processor is employed to separate tire rotation information for other types of strain induced signals that may be produced by the piezoelectric sensor (250).
