The STMicroelectronics' IIS3DWB (201-0404)
system-in-package (SiP) features a 3-axis digital vibration sensor with an ultra-wide and flat frequency range of up to 6kHz. The device is well suited for vibration monitoring and predictive maintenance applications within the industrial environments due to wide bandwidth, low noise, very stable and repeatable sensitivity as well as the capability of operating over an extended temperature range (up to +105 °C).
Key features
3-axis vibration sensor with digital output
User-selectable full-scale: ±2/±4/±8/±16 g
Ultra-wide and flat frequency response range: from dc to 6 kHz (±3 dB point)
Ultra-low noise density: down to 75 µg/√Hz in 3-axis mode / 60 µg/√Hz in single-axis mode
High stability of the sensitivity over temperature and against mechanical shocks
Extended temperature range from -40 to +105 °C
Low power: 1.1 mA with all 3 axes delivering full performance
SPI serial interface
A low-pass or high-pass filter with a selectable cut-off frequency
Interrupts for wake-up / activity - inactivity / FIFO thresholds
Embedded FIFO: 3 kB
Embedded temperature sensor
Embedded self-test
Supply voltage: 2.1 V to 3.6 V
Compact package: LGA 2.5 x 3 x 0.83 mm 14-lead
ECOPACK, RoHS and “Green” compliant
The IIS3DWB vibration sensor is featured on the STWIN SensorTile wireless industrial node (STEVAL-STWINKT1B) (210-2301)
development kit, making it even easier to develop your predictive maintenance and condition monitoring applications.

I used a similar technology 25-30 years ago in heavy industry and it was very effective
