WebGeomagnetic sensors are sensors that detect the magnetic field of the Earth, and are commonly referred to as electronic compasses. Geomagnetic sensors can determine direction by detecting the geomagnetic field. Geomagnetic sensors include 2-axis types (X and Y) and 3-axis models with a Z axis that measures the magnetic force in that direction. Mobile phones are low-powered radiofrequency transmitters, operating at frequencies between 450 and 2700 MHz with peak powers in the range of 0.1 to 2 watts.
