Smart sensor: BHI380

Small. Low-power. Self-learning AI software.


Self-learning AI smart sensor with integrated IMU

BHI380 is a programmable IMU-based AI sensor system combining a gyroscope with an accelerometer that enables full customization. The integrated sensor fusion library enables 3D audio with head orientation for personalized sound experiences as well as simple gesture recognition. It can be used in wearables and hearables, smartphones and tablets, smart devices and more.

The BHI380 is the PRO variant of BHI360 featuring a larger set of integrated application specific algorithms: BHI380 is based on the same architecture but also includes self-learning AI software suitable for a wide variety of fitness tracking, thus making training and tracking a breeze and enabling personalized workouts. Dedicated swim tracking software measures swimming style and boosts users to the next fitness level in the water, while the pedestrian dead reckoning (PDR) algorithm helps users reach their destination, even when the GPS signal drops out for a few minutes.

The sensor is provided in a compact 20-pin LGA package measuring 2.5 x 3 x 0.95 mm³. This means it is 50% smaller than its previous generation, and that it is the smartest programmable IMU sensor in the market. BHI380 is a highly integrated, ultra-low power, smart 6-axis IMU consisting of a 32-bit programmable microcontroller. In addition, it consists of an ultra-low power microprocessor, including pre-installed sensor fusion software and algorithms in a single package.
