Digital compasses integrate motion and magnetic sensing in a small package for portables
STMicroelectronics expanded its sensor portfolio with a compact e-compass module. The integration of motion and magnetic sensing in a 3 mm x 3 mm x1 mm package is positioned as opening new possibilities for advanced navigation and location-based services in ever-sleeker portable consumer devices. The ST e-compass’ ability to provide accurate heading information - indicate the direction in which a person or vehicle is moving - enables applications such as pedestrian dead-reckoning, map/display orientation, and direction finding. Tied to location-based service apps, compassing capabilities can help consumers identify and retrieve information on nearby points of interest, such as historical or geographical points of interest, restaurants or shops, by simply pointing their GPS-equipped mobile devices in the direction of the object concerned. Advanced features include two programmable interrupt signals that enable immediate notification of motion detection, click/double-click events, and other conditions.
