New IIS3DWB sensing solution for wide scale adoption of vibration monitoring in Industry 4.0 applications
Optimized for high performance industrial vibration sensing, the 3-axis IIS3DWB MEMS accelerometer with an ultra-wide bandwidth and low-noise is a power-efficient and affordable digital sensing solution included in ST’s 10-year longevity program.
The IIS3DWB sensor is a key enabler of industrial vibration monitoring:
· it offers a 3-axis digital plug-and-play solution for a seamless and cost-effective adoption
· its wide and flat frequency response up to 6kHz and low noise ensure high-quality vibration data is collected
· the sensor low-power and extended temperature range up to +105°C is ideal for long-lasting, self-powered wireless sensor nodes and allows them to be retrofitted into existing systems
The STEVAL-STWINKT1 development kit takes the prototyping of vibration monitoring solutions to the next level by integrating the IIS3DWB sensor with numerous additional sensors and an ultra-low-power STM32L4+ MCU, and offering wired and wireless connectivity. Software libraries for vibration processing are also available, including a high-speed data logger for data scientists to develop algorithms.
