Motion sensor hub optimizes and operates multiple motion sensors
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. The chip 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. Sentral makes the integration of 9-axis sensor systems faster and easier, and at the same time, improves the quality, reliability and utility 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, it supports a maximum data update rate of 400Hz. In normal operation, the 1.6×1.6×0.5mm chip draws 350µA while the standby mode draws 5µA. The IC can support a wide variety of gyros, accelerometers 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.
