What is magnetic sensor?
Magnetic sensor includes a sensing chip having a magneto resistive element for sensing a magnetic vector and a magnet for biasing the magnetic vector sensed by the magneto resistive element.
The sensing chip senses change in the magnetic vector for detecting a behavior of a magnetic body based on a variation of a resistance value of the magneto resistive element when biasing of the magnetic vector is caused by the magnet in cooperation with the magnetic body that is in motion in proximity of the sensing chip.
Magnetic sensor is used for compass functionality. Compass functionality is available in Navigation menu.
