STMicroelectronics released the IIS3DWB, a new vibration-sensing solution for maintenance of factory equipment.

The company’s new vibration sensor and supporting STEVAL-STWINKT1 multi-sensor evaluation kit was developed for the acceleration of condition-monitoring systems.

According to the company, the IIS3DWB is a 3-axis MEMS^[1] 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.

Key features of the IIS3DWB:

• Accelerometer with wide and flat frequency response over 3-axis saves external signal conditioning and complexity needed by competing sensors
• Digital plug-and-play capability, integrating signal conditioning, analog-to-digital converter (ADC), filtering, and bandwidth equalization on-chip
• Low noise: 75µg/√Hz in 3-axis mode or 60µg/√Hz in single-axis mode selectable on the fly
• -40°C to 105°C operating-temperature range
• 1.1mA operating current at full performance in all three axes

Features of the STEVAL-STWINKT1:

• Ultra-low-power Arm® Cortex®-M4 MCU (STM32L4R9ZI) running at 120MHz with FPU, 2048 kbytes Flash, and optimized power management
• On-board footprint for STSAFE-100 secure element IC for secure connection and authentication
• Wireless BLE4.2 on-board and wired RS485 and USB OTG connectivity
• High-speed data logging with real-time storage on SD-CARD and streaming via USB of data from multiple (22) sensors at their maximum resolution (ODR)
• Companion cloud application and dashboard
• Optional Wi-Fi expansion board (STEVAL-STWINWFV1), and STMod+ cellular expansion board from the P-L496G-CELL02 kit
