STMicroelectronics LIS2DH12

The LIS2DH12 is an ultra-low-power high-performance three-axis linear accelerometer belonging to the “femto” family with digital I2C/SPI serial interface standard output. The LIS2DH12 has user-selectable full scales of ±2g/±4g/±8g/±16g and is capable of measuring accelerations with output data rates from 1 Hz to 5.3 kHz.

The self-test capability allows the user to check the functionality of the sensor in the final application.

The device may be configured to generate interrupt signals by detecting two independent inertial wake-up/free-fall events as well as by the position of the device itself.
