STMicroelectronics IIS3DWB 3-Axis Digital Vibration Sensors
STMicroelectronics IIS3DWB 3-Axis Digital Vibration Sensors are a system-in-package solution featuring low noise, over an ultra-wide, and flat frequency range. Implementing the wide bandwidth, low noise, very stable, and repeatable sensitivity, together with the capability of operating over an extended temperature range (up to +105°C), makes the IIS3DWB ideal for vibration monitoring in industrial applications.
The STMicroelectronics IIS3DWB 3-Axis Digital Vibration Sensors deliver high performance, low power consumption, and embedded digital features such as FIFO and interrupts. This makes the IIS3DWB particularly suitable for battery-operated industrial wireless sensor nodes. The 3kB first-in, first-out (FIFO) buffer is integrated into the device to avoid data loss and limit the intervention of the host processor.
The sensor has a selectable full-scale acceleration range of ±2/±4/±8/±16g. Additionally, the IIS3DWB is capable of measuring accelerations with a bandwidth up to 6kHz with an output data rate of 26.7kHz.
