A magnetic sensor is a small-scale micro-electrochemical system (MEMS) device for detecting and measuring magnetic fields. This sensor acts as a transducer which varies its output voltage in reaction to a magnetic field. These type of sensors are used for proximity switching, speed detection, positioning, and current sensing applications. Moreover, these sensors also detect changes and disturbances in a magnetic field, like flux, strength, and direction. This report includes magnetic sensors which are based on Hall Effect, AMR (Anisotropic Magneto-Resistive), GMR (Giant Magneto-Resistance), and TMR (Tunnel Magneto-Resistance) technologies.
