Description
The H3LIS331DL is a low-power high-
performance 3-axis 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-wakeup functions.
The H3LIS331DL has dynamically user-
selectable full scales of ±100g/±200g/±400g and it
is capable of measuring accelerations with output
data rates from 0.5 Hz to 1 kHz.
The H3LIS331DL is available in a small thin
plastic land grid array package (LGA) and it is
guaranteed to operate over an extended
temperature range from -40 °C to +85 °C.
Applications
Shock detection
Impact recognition and logging
Concussion detection
