STMicroelectronics has introduced the LSM6DSV16X, a six-axis IMU which features advanced artificial intelligence (AI) capabilities for smart motion sensing in IoT devices at the edge of the network.
The IMU is ideal for functions such as motion tracking and gesture detection, indoor navigation, image stabilization, and vibration monitoring and compensation.
The LSM6DSV16X includes standard IMU components: a three-axis digital accelerometer and a three-axis digital gyroscope. But on top of this, ST has built in a triple core for processing acceleration and angular rate data on three separate channels, the user interface, optical image stabilization, and electronic image stabilization, with dedicated configuration, processing, and filtering functions.
The AI capabilities of the LSM6DSV16X also enable it to apply edge computing functions to the raw motion data that it captures. Its finite state machine (FSM) performs configurable motion tracking, while a machine learning core (MLC) supplies context awareness, and provides exportable AI features for IoT applications.
The LSM6DSV16X supports the adaptive self-configuration feature, which allows the FSM to automatically reconfigure the IMU in real time based on the detection of a specific motion pattern. Reconfiguration can also be driven by the output of a specific decision tree configured in the MLC, without any intervention from the host processor.
The embedded Qvar function detects variation in electric charge, for user interface functions such as tap, double-tap, triple-tap, long press, or L/R or R/L swipe.
The LSM6DSV16X features an analog hub which can interface to an external analog input and convert the input to a digital signal for processing.
The SensorTile.box PRO from STMicroelectronics is a new programmable wireless box kit for developing IoT remote data acquisition applications. It features components for motion and environmental data sensing, as well as a digital microphone, alongside Bluetooth® Low Energy 5.2 and NFC connectivity.
ST supplies the SensorTile.box PRO with a number of ready-made embedded IoT applications. With the free STBLESensor smartphone app, designers can immediately control various motion, environmental, and pressure sensing applications, perform data logging, and run AI algorithms for a baby crying detector, and human activity recognition.
Developers can also build custom applications through the STBLESensor app, or in the STM32 open development environment with the support of ST function pack libraries.
