Overview
The LIS331DLH is an ultra low-power, high-performance three-axis linear accelerometer from STMicroelectronics, belonging to the "nano" family. It features a digital I2C/SPI serial interface and is designed for advanced power saving and smart sleep to wake-up functions. This accelerometer is capable of measuring accelerations with dynamically user-selectable full scales of ±2g, ±4g, and ±8g, and it supports output data rates from 0.5 Hz to 1 kHz. The device includes a self-test capability, 6D orientation detection, and high shock survivability up to 10000 g. It is available in a small thin plastic land grid array (LGA) package and operates over an extended temperature range from -40 °C to +85 °C.
