Smart New Sensor Fusion Chip Makes It Practical to Integrate and Optimize Multiple Motion Sensors on Mobile Devices.
PNI Sensor Corporation and EM Microelectronic 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, Sentral eliminates the need for complex sensor calibration and algorithm development. Further, it dramatically reduces power usage, offloading sensor fusion work from less efficient host CPU.
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, improves the quality and reliability of output from the accelerometers, gyroscope and geomagnetic sensors. Compatible with Android and Windows 8-based mobile products, Sentral delivers the most accurate (2º 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 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. Now manufacturers are not tied to a single source or sensor type. Because it uses 350 µA of power in normal operation, it frees up valuable CPU power and battery life, and with 1.6 × 1.6 × 0.5mm footprint, it takes up virtually no space.
