Description
The LIS331DLM is an ultra low-power high performance three axes linear accelerometer belonging to the “nano” family, with digital I2C/SPI serial interface standard output.
The device features ultra low-power operational modes that allow advanced power saving and smart sleep to wake-up functions.
The LIS331DLM has dynamically user selectable full scales of ±2g/±4g/±8g and it is capable of measuring accelerations with output data rates from 0.5 Hz to 400 Hz.
The self-test capability allows the user to check the functioning of the sensor in the final application.
