A Case Study: MR vs. Hall Effect for Position Sensing

From iC-Haus Corporation
 

 
While both magnetoresistive and integrated Hall sensors measure the strength of magnetic field components, they do so in different ways and this can directly affect their successful use in a position sensing application. Choosing which of the two is a better fit for your application may require you to consider sensor characteristics that don't show up on manufacturers' data sheets.
