Accelerometers have advanced power-saving features that make them the ideal choice for ultra-low-power applications. These features include low-power mode, auto wake-up function and FIFO buffer that can be used to store data, thus reducing the host processor loading and system power consumption.

ST’s accelerometers are suitable for handheld portable applications such as mobile phones and PDAs, or any other application where low power consumption and reduced package size are required. The new generation of accelerometers, recently introduced by ST, makes a significant step forward in miniaturization, with packages sized only 2x2x1 mm, available with both 14 and 12-leads pinout.

ST’s portfolio also includes accelerometers for automotive applications, such as the AIS32x family, with extended temperature range and AEC-Q100 qualified, and IISxxx products, that are part of ST’s longevity program and will stay in production for ten years from the date of introduction.

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.
