New Motion Sensor Hub for Mobile Devices

March 6, 2013

PNI Sensor and EM Microelectronic are introducing the Sentral smart sensor fusion chip, designed to integrate, optimize, and operate multiple motion sensors on mobile devices.

SANTA ROSA, CA and MARIN, SWITZERLAND /Marketwire/ -- PNI Sensor Corp. and EM Microelectronic-Marin SA announce the introduction of the Sentral sensor fusion hub, a new, highly effective way to integrate complex motion sensors on mobile devices. The Sentral sensor fusion hub is the "first hub designed specifically to manage sensor outputs on a low-power integrated circuit, making 9-axis motion sensing outputs both super-precise and practical to implement. Carrying top-of-the-line sensor fusion algorithms on an extremely low-power integrated circuit, Sentral eliminates the need for complex sensor configurations, calibrations, and algorithm development. Further, it dramatically reduces power usage, offloading sensor fusion work from less-efficient host CPUs or sensor CPUs onto an ultra-low-power IC tailor-made for sensor optimization.

This is welcome news for mobile device manufacturers, as Sentral makes the integration of 9-axis sensor systems faster and easier, and at the same time, it improves the quality, reliability, and utility of output from accelerometers, gyroscopes, and geomagnetic sensors. Compatible with Android- and Windows 8-based mobile products, Sentral delivers the "most accurate (2° of heading accuracy), real-time motion-related data available."

Further, because it is designed and built specifically to meet the power needs of the mobile market, the Sentral IC is ultra-low-power and consumes less than 10% of the power used by other CPUs performing the task of sensor fusion. It maximizes battery life even for applications that need constant processing of sensor data.

Sentral makes sensor implementation more practical as well. It can support a wide variety of gyros, accels, and magnetic sensors from multiple and changing vendors. This allows for separate placement of the sensors, and manufacturers are not tied to a single source or sensor type. Because it uses a mere 800 mA of power in normal operation, it frees up valuable CPU power and battery life, and with a mere 1.6 by 1.6 by 0.5 mm footprint, it takes up virtually no space.
