- Low Power Consumption
Offloads sensor processing from the less efficient host CPU, consuming <1% of the power of a Cortex M0 running a comparable sensor fusion algorithm. Provides the ability to tailor the tradeoff between power consumption and motion-tracking performance.
- Industry Leading Accuracy
Unparalleled heading accuracy for consumer electronics applications.
- Continuous hard and soft-iron magnetic auto-calibration
Provides continual background calibration of the sensors. Leverages PNI’s more than 20 years of experience and expertise in magnetic measurement.
- Magnetic anomaly compensation
Heading and motion tracking is unaffected by magnetic anomalies such as rebar in buildings, desks, speakers etc., that can easily throw off the accuracy. SENtral recognizes and compensates for these anomalies.
- Sensor Flexibility
Works with the most common consumer electronic MEMS motion sensors, so system designers can choose the sensors most appropriate for their systems.
- Small Form Factor
1.6x1.6x0.5 mm chip-scale package on 0.4 mm pitch. Uses little PCB real estate, allowing for painless integration.
- I2C Interface
Uses the industry-standard I2C protocol in a proprietary low-power implementation to interface to the sensors and the host, so system integration is straightforward. Standard, Fast, Fast Plus, and High Speed are supported on the host bus.
SENtral natively outputs quaternions, rotational velocity, linear acceleration, and magnetic field.
