Low-power six-axis sensor supports motion detection and gesture recognition

The STMicroelectronics LSM6DSO16IS is a system-in-package which combines a three-axis digital accelerometer and a three-axis digital gyroscope. It also includes an innovative sensor signal processing unit for implementing AI algorithms at the edge.

The low-power features of the LSM6DSO16IS mean that in always-on mode it provides optimal results in personal electronics equipment and IoT devices while extending battery run-time. It can be used for complex motion detection and gesture recognition, and for activity recognition and tracking. 

The LSM6DSO16IS has a full-scale acceleration range of ±2 g/±4 g/±8 g/±16 g and an angular rate range of between ±125 degrees/s and ±2,000 degrees/s. The module provides a set of programmable interrupt functions. An on-chip sensor hub manages the inputs from up to six sensors: the internal accelerometer and gyroscope, and four external sensors.

The LSM6DSO16IS embeds a new ST signal processing block, the intelligent sensor processing unit (ISPU), to provide real-time sensor data to the host application. The ISPU is an ultra low-power, high-performance programmable core which can execute signal processing and artificial intelligence (AI) algorithms at the edge. The ISPU supports C programming, and is backed by an ecosystem of libraries and third-party tools and development environments. Its circuitry is optimized for the real-time execution of algorithms, providing a streamlined implementation of AI in wireless sensor nodes.
