IIS3DWB MEMS vibration sensor optimized for industrial monitoring Plug-and-play evaluation kit accelerates application development Convenient and economical solution for condition-based maintenance
STMicroelectronics (NYSE: STM), a global semiconductor leader serving customers across the spectrum of electronics applications, is powering the next generation of Industry 4.0 applications with a new vibration-sensing solution optimized to enable smart maintenance of factory equipment.
ST’s IIS3DWB vibration sensor and supporting STEVAL-STWINKT1 multi-sensor evaluation kit accelerate development of condition-monitoring systems that boost productivity by inferring equipment maintenance needs. Analyzing the sensed vibration data locally or in the cloud helps owners create strategies that maximize uptime, minimize servicing costs, and avoid emergency repairs.
The IIS3DWB is a 3-axis MEMS accelerometer optimized for industrial vibration sensing. The STEVAL-STWINKT1 simplifies prototyping and testing by integrating the IIS3DWB with additional sensors, an ultra-low-power microcontroller and algorithms for vibration processing, Bluetooth® wireless module, and USB connection. Housed in a plastic enclosure with a battery, the kit is ready to begin application development and presents a convenient reference design. High-speed data-logger and cloud-dashboard utilities are included to help collect, analyze, and visualize the results.
The IIS3DWB vibration-sensing system-in-package is in production now and available for $9.00 in a 14-lead plastic land grid array (LGA) package. The STEVAL-STWINKT1 is available from ST for $99.00.
Further technical information
ST’s state-of-the-art IIS3DWB 3-axis ultra-wide-bandwidth MEMS accelerometer detects vibrations that are prime indicators of a machine’s service requirements. The device, which is covered under ST’s 10-year availability assurance for industrial products, is optimized for vibration monitoring. The frequency response is tailored to be fully flat and with low noise up to 6kHz and then with a sharp cutoff and high attenuation to remove frequency-aliasing concerns and to detect machine-related faults with accuracy and consistency. Low power consumption maximizes the operating lifetime of independently powered sensor nodes. Key features of the IIS3DWB include:
Leveraging ST’s leading position in MEMS technology, the STEVAL-STWINKT1 evaluation kit integrates multiple miniature sensors on-board in addition to the IIS3DWB. There is also a Bluetooth® Low Energy (BLE) radio for connecting to an edge device or directly to the Internet. The many on-board features let solution integrators bypass labor-intensive sensor integration to focus on their application and accelerate time to market and offer advanced software features like high-speed data logging for the benefits of new field of exploration like machine learning and AI. The price of the kit is more than 75% less than some alternatives in the market and eliminates a significant cost barrier to Industry 4.0 digital transformation.
