IIS3DWB10IS: advanced vibration sensor for next-gen predictive maintenance

Turn vibration data into faster, smarter maintenance decisions

In smart manufacturing and industrial Internet of Things (IoT), real-time, high-fidelity vibration monitoring is essential for predictive maintenance and operational efficiency. New MEMS vibration sensing technologies now deliver piezoelectric-like performance with ultrawide bandwidth, high dynamic range, and ultralow noise. These technologies also add digital edge-computing capabilities for simpler and more cost-effective designs. ST’s IIS3DWB10IS combines high-precision sensing with ISPU 2.0 and hardware accelerators, enabling real-time AI processing and advanced analytics directly at the edge. This capability allows customers to make faster decisions, reduce system complexity, and lower maintenance costs.

High-performance sensor with in-sensor AI capability

The IIS3DWB10IS captures vibration data with high clarity, enabling earlier detection of issues and faster decision-making. Its ultrawide bandwidth and high-resolution sensing support reliable monitoring of a wide range of machine behaviors, while ISPU 2.0 brings real-time edge processing directly on the device.
