IIS328DQ 3-Axis Linear Accelerometer STMicroelectronics IIS328DQ 3-Axis Linear Accelerometer is an ultra-low-power high-performance accelerometer. The IIS328DQ is digital serial interface, SPI or I2C compatible and recommended for industrial applications that require an extended temperature range and long lifespan. The ultra-low-power operational modes allow advanced power saving and smart sleep-to-wakeup functions. The accelerometer has dynamic user-selectable ±2g /±4g /±8g full-scales and can measure accelerations with output data rates from 0.5Hz to 1kHz.
