Abstract
Systems and methods for detecting a magnetic target include a plurality of magnetic field sensing elements arranged about a central point. Each one of the plurality of magnetic field sensing elements is configured to measure a magnetic field produced by a magnetic target and provide a respective output signal that represents a respective measurement of a strength of the magnetic field. A processor circuit is coupled to receive the output signal from each one of the plurality of magnetic field sensing elements and determine a barycenter of the measurements of the magnetic field based on a position of the magnetic field sensing elements.
