Overview
The H3LIS331DL, manufactured by STMicroelectronics, is a high-g, low-power, high-performance 3-axis linear accelerometer. It features a digital I²C/SPI serial interface and is part of the 'nano' family of accelerometers. This device is designed for advanced power saving with ultralow-power operational modes and smart sleep-to-wake-up functions. It is capable of measuring accelerations with dynamically user-selectable full scales of ±100g, ±200g, and ±400g, and output data rates ranging from 0.5 Hz to 1 kHz. The H3LIS331DL operates over an extended temperature range from -40°C to +85°C and is housed in a small thin plastic land grid array (LGA) package.
