Description
The LIS331HH is an ultra low-power high performance high full-scale 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 LIS331HH has dynamically user selectable full scales of ±6g/±12g/±24g and it is capable of measuring accelerations with output data rates from 0.5 Hz to 1 kHz. The self-test capability allows the user to check the functioning of the sensor in the final application.
