The HSCDTD004A geomagnetic sensor from Alps Electric has a high-precision magnetic element optimised to enhance sensor output. The HSCDTD004A geomagnetic sensor enables electronic compass functions in smartphones and tablet PCs.
Many mobile phones and smartphones contain navigation applications or applications used to indicate a user's current location. These applications require a global positioning system for pinpointing the user's location and an electronic compass for detecting the direction of the device. Geomagnetic sensors are required to be very accurate in order to provide good azimuth reading.
According to the company, the geomagnetic sensor has an optimised magnetic element to increase sensor output. This improves the azimuth detection accuracy and helps in reducing the calibration time. The geomagnetic sensor has a measurement range extended to ±1.2mT and contributes to improved set layout flexibility within magnetic field environments, claims the company. It is also compatible with inter-integrated circuit and serial peripheral interface.
