Bosch BHI360 inertial measurement unit (IMU) smart sensor

Mouser Electronics, Inc. now stocks the BHI360 programmable inertial measurement unit (IMU) smart sensor from Bosch. The sensor is an intelligent sensor system that delivers a high performance-to-power consumption ratio, yet is simple to integrate due to its small size and built-in, ready-to-use software algorithms. The highly-integrated, ultra-low-power sensor can be customised for a range of applications, including wrist wearable devices, head-mounted devices, smartphones and AR/VR/MR headsets.

The IMU smart sensor combines a gyroscope with an accelerometer to enable full customisation. The integrated sensor fusion library allows 3D audio with head orientation for personalised sound experiences, as well as simple gesture recognition.

The sensor also features an integrated, low-power custom processor. This processor can run simpler sensor processing algorithms, such as gesture detection or step counting, thus avoiding waking the central device processor and keeping power consumption low. The custom processor also helps achieve better power consumption for high-end algorithms.

The sensor provides fast SPI (50 MHz) and I2C (3.4 MHz) host interfaces and multiple SPI, I2C and GPIO interfaces for external sensors. The device is housed in a compact 20-pin LGA package measuring 2.5 x 3.0 x 0.95 mm, making it suitable for space-constrained applications. Typical total current consumption is less than 600 μA for 3D orientation.

The smart sensor is supported by the BHI360 Shuttle Board 3.0, available to order from Mouser. The Shuttle Board 3.0 also includes a BME688 AI-based environmental sensor, a BMM350 magnetometer and a pressure sensor. The BHI360 Shuttle Board 3.0 allows easy access to sensor pins via a simple socket and can be directly plugged into the Bosch Application Board 3.0 sensor prototyping platform.
