What is a Geomagnetic sensor?

A geomagnetic sensor is a device that detects the Earth's magnetic field to measure direction. It plays a crucial role in recognizing orientation, commonly used in smartphones and vehicle navigation systems. Geomagnetic sensors mainly utilize magnetoresistance or Hall effect to detect geomagnetism and provide accurate directional information. Their compact and energy-efficient design allows integration into various portable devices.
