The BMC056 is a low power and low noise 6-axis digital compass. It measures the earth’s geomagnetic field as well as dynamic and static acceleration in all three dimensions and outputs tilt-compensated heading or orientation information.
BMC056 is housed in a package with a footprint of 3 x 3 mm² and 0.95 mm height. The integrated accelerometer provides all functionalities of Bosch Sensortec’s leading-edge 12-bit digital accelerometer, including a 32 frame FIFO buffer storing acceleration data. Due to its advanced power management, BMC056 is ideally suited for virtual reality and navigation applications, motion tracking, shock and vibration detection in handhelds like mobile phones, tablets, notebooks, portable media players, man-machine interfaces and game controllers.
Applications
- Augmented reality applications and locationbased services
- Indoor and outdoor navigation, e.g. map rotation or step counting (pedometry)
- Motion tracking
- Gesture recognition e.g. tap and double tap sensing, Display profile switching
- Gaming
- Air mouse applications, pointing devices
Would you like to check an altitude on a map and plan the the best route or check the local weather forecast for your next hike? Are you monitoring your daily sports acitivities with your smartphone? These and many more outdoor applications are enabled by MEMS sensors. These new and advanced devices will even help you to find your car in a public parking garage.
The 6-axis BMC156 is an small and low power digital compass with a footprint of merely 2.2 x 2.2 mm² and 0.95 mm height as well as a 12 bit digital resolution. Due to its pin-compatible pin-out it fits well on a 2x2 mm² standard accelerometer landing pattern (BMA).
