STMicroelectronics IIS3DWBG1 Vibration Sensor
STMicroelectronics IIS3DWBG1 Vibration Sensor is a 3-axis digital vibration sensor with low noise over an ultrawide and flat frequency range. This sensor offers a selectable full-scale acceleration range of ±2g/±4g/±8g/±16g and is capable of measuring accelerations with a bandwidth up to 6kHz. The IIS3DWBG1 vibration sensor delivers high performance at low power consumption with the digital output. This sensor integrates a 3kB First-In, First-Out (FIFO) buffer to prevent data loss and reduce host processor intervention. The IIS3DWBG1 vibration sensor features ultralow noise density of 75µg/√Hz in 3-axis mode and 60µg/√Hz in single-axis mode. This sensor is available in a 14-lead plastic, Land Grid Array (LGA) package. Typical applications include industrial equipment, electric or hybrid vehicles, condition monitoring, test and measurements, and predictive maintenance.
