Abstract
In this paper, a low-cost, effective microcontroller digital solution is presented to improve the accuracy and reliability of the anisotropic magnetoresistive (AMR) sensor. The proposed approach eliminates the inaccuracies caused by the nonidentical thin-film stripes of the Wheatstone bridge and minimizes the effect of nonlinearities, hysteresis and temperature drifts.
