A custom IC that performs sensor fusion using less than 1% of the power a general purpose microprocessor uses.

Carrying top-of-the-line sensor fusion algorithms on an extremely low-power integrated circuit, Sentral dramatically reduces power usage by offloading sensor management and fusion work from less efficient host CPUs onto an ultra low-power IC tailor-made for motion processing. And it reduces the need for complex algorithm development and calibration. The result is the first ultra low-power integrated circuit to make 9-axis motion sensing extremely accurate in real world conditions — while dramatically reducing processing power use of the host CPU.

Why is it needed?

Increasing use of gyroscopes, accelerometers and magnetic sensors is enabling greater functionality across a wide spectrum of mobile devices and applications. Yet effective fusion of these sensors often drains valuable host CPU power needed for other functions.

Why is adding sensors hard?

For many OEMs, working out the subtleties of sensor integration, signal enhancement, calibration, magnetic interference, sensor drift and power consumption has proven to be time consuming, difficult and expensive work. Additionally, the job of managing and “fusing” data from these multiple sensors is left to the host CPU, eating up valuable power and space, even if the algorithms prove to work.

Sentral makes it work.

By managing all three sensors, Sentral outputs heading and accurate absolute and relative motion tracking data – all with more accuracy and reliability than you’ve ever experienced. Using “constant calibration” technology, it polls the individual sensors, integrating, fusing and filtering their data with state-of-the art patented Kalman filter algorithms. Created and designed by sensor fusion experts with more than 20 years of real world experience, Sentral’s output is fast, accurate and very reliable.

Sentral is a power-savior.

Used in small form factor devices, it makes your sensors work better and frees up valuable CPU power in mobile applications. The Sentral IC is ultra low power, consuming 1% of the power of standard CPUs performing the task of sensor fusion. Plus it’s tiny.

Works with the sensors you use.

The Sentral Sensor Fusion Hub makes it practical because it supports a wide variety of gyroscopes, accelerometers and magnetic sensors from multiple vendors. It doesn’t require you to change out to new sensors.
