GENEVA, Switzerland, Nov 10, 2025 – STMicroelectronics has launched the ISM6HG256X, a three-in-one motion sensor for industrial IoT applications. The device combines low-g (±16g) and high-g (±256g) acceleration detection with a gyroscope to measure fine vibrations and severe impacts, improving motion and shock detection in industrial systems.
The ISM6HG256X is designed for industrial IoT applications, including asset tracking, worker safety devices, condition monitoring, robotics, and factory automation and black box event recording. It integrates a dual-range accelerometer and gyroscope to reduce sensor count and simplify system design. Embedded edge processing enables real-time event detection and adaptive sensing for equipment monitoring and automated factory systems.
“Traditional solutions require multiple sensors to cover low and high acceleration ranges, increasing system complexity, power consumption, and cost. The ISM6HG256X addresses these challenges by providing a single, highly integrated sensor,” said Simone Ferri, APMS group VP & MEMS sub-group GM, STMicroelectronics. “These new sensing dimensions, made possible also in harsh environment, combined with machine-learning running inside the IMU sensor itself, allows to quickly recognize, track and classify motion, activities and events while using very little power, helping businesses make smart, data-driven decisions as they move toward digital transformation.”
Edge AI plays a key role in STMicroelectronics’ MEMS development, improving processing speed, energy efficiency and security through local data handling while enabling sensing and IoT integration for connected devices.
ST holds more than 600 micro-electromechanical systems (MEMS) patents and manages in-house production. The company developed the ISM6HG256X, which combines 16g and 256g accelerometers with a MEMS gyroscope for angular rate measurement.
Technical Information
The ISM6HG256X contains the machine-learning core (MLC) and finite state machine (FSM), together with self-configuration (ASC) and sensor fusion low power (SFLP). These features integrate edge AI into the sensor to classify motion events with low latency and minimal power use. The technology can reconstruct signal patterns for motion tracking. With the built-in SFLP algorithm, the sensor can also perform 3D orientation tracking with a few µA of current.
ST’s X-NUCLEO-IKS5A1 industrial expansion board with MEMS studio design environment and software libraries, X-CUBE-MEMS1, are available to assist developers, helping implement functions including high-g and low-g fusion, sensor fusion, context awareness, asset tracking, and calibration.
The ISM6HG256X is available in a 2.5mm x 3mm surface-mount package to withstand harsh industrial environments from -40°C to 105°C.
