Weeks meritorious compass module, electronic compass system magnetic field sensor magnetoresistive (MR) technology is the best solution, compared to many electronic compass still using fluxgate sensor the MR technology does not require coil and can be used IC production process (IC-like process) production is a more worthy use solution. Since the MR has high sensitivity, it is even better than a Hall element in the scope of this application. The Philips semiconductor KMZ52 is a two-dimensional magnetic field sensor, it is the reluctance as well as its sensitivity and linearity to measure weak Earth' s magnetic field, and the integration of the set/reset function and the compensation coil, these coils can be used to flip (flipping) technology to eliminate the offset, sensitivity to temperature drift with electromagnetic feedback technology to eliminate.
