Description:

The IIS3DWBTR Digital Accelerometeris a rugged, industrial-grade, 3-axis digital vibration sensor designed for demanding applications. Its ultrawide bandwidth and exceptionally low noise performance ensure accurate vibration monitoring across a broad frequency range. With stable sensitivity and operation up to +105C, it’s ideal for predictive maintenance and condition monitoring in harsh industrial environments.

Low power consumption, digital output, and integrated features like FIFO and interrupts make it perfect for battery-powered wireless sensor nodes. Typical uses include machine health monitoring, test and measurement, and a variety of other industrial vibration analysis tasks.
