Bosch BHI160B

BHI160(B) is a compact, low-power smart hub integrating a triaxial gyroscope, triaxial accelerometer, and programmable MCU. It comes pre-loaded with software and dedicated algorithms for activity recognition, specifically designed to enable always-on motion sensing. The device is ideal for smartphones, wearables, and other applications requiring high-accuracy real-time motion data at extremely low power consumption. It combines Bosch's best-in-class 6-axis IMU (BMI160) with an MCU — the new Bosch sensor fusion core — enabling a complete Android sensor stack on-device even without an Android OS or Android environment. Combined with built-in computational capability and highly configurable on-board memory, the BHI smart hub delivers a low-power solution for motion sensing and data processing.

• Integrated smart hub solution for always-on motion sensing, consuming only a fraction of the power typically required by discrete component implementations.
• 32-bit floating-point MCU (fusion core) optimized for data fusion, motion sensing, and activity recognition at ultra-low power, designed to offload power-intensive data processing from the main application processor to the smart hub.
• Robust BSX sensor fusion library integrated in ROM to reduce design complexity and accelerate time-to-market.
• Additional software and algorithms for RAM processing, provided as ready-to-use firmware patch files; visit the website for available downloads.
• On-board computation capability for data fusion, 3D and absolute orientation, rotation vector, quaternion, and Euler angle calculations.
• Recognition of significant motion, tilt, pick-up, wake, and glance gestures, enabling gesture-based HMI for smartphones and wearables.
• Recognition of activities including standing, walking, running, cycling, and in-vehicle travel, suitable for health and fitness applications or other use cases requiring high-accuracy, reliable detection and/or monitoring of user activities.
• Step detection and counting functionality.
• Android 5/L/Lollipop and Android 6/M/Marshmallow support (non-HiFi), including batching with dual FIFO buffers for wake-up and non-wake-up events, with full Android sensor stack support even without an Android OS or other Android environment.
• High-speed I²C interface with data rates up to 3.4 MBit/s for efficient, low-power data transfer.
• Highly configurable internal RAM for feature expansion and/or FIFO data buffering.
• Software/firmware-based functionality supporting updates, optimization, customization, and upgrades for future requirements.
• Smart hub, MCU, MEMS sensors, and software highly integrated in a 3.0×3.0×0.95 mm³ LGA package with expansion interface for additional sensors.

• Activity recognition (standing, walking, running, cycling, vehicle riding)
• Step counting, indoor navigation, dead reckoning
• HMI (gesture detection for wearables)
• Augmented reality, immersive gaming
• Tilt-compensated electronic compass
