Abstract :
Magnetic field measurement constitutes a good method to obtain some magnitudes related to it. In this work we present the design of an instrumentation system with the aim to characterize several properties of these magnetoresistance sensors. Experimental results derived from the characterization process are shown and various novel measurement and control applications of these sensors are obtained
