LIS331DLHTR屬于傳感器變送器的運動傳感器-加速計。由意法半導體集團制造生產(chǎn)的LIS331DLHTR運動傳感器 - 加速計加速度計用于檢測并響應運動或振動等加速度的變化。加速度計類型有 X、Y 或 Z 軸上的模擬或數(shù)字加速度計，加速度范圍為 ±0.5 g 至 ±2000 g，靈敏度為 1 至 500 k (LSB/g)，輸出類型有模擬電壓、藍牙、數(shù)字、DSI、IEPE、I2C、PCM、PWM、射頻和 SPI。

Description

The LIS331DLH 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 LIS331DLH 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 1 kHz.

The self-test capability allows the user to check the functioning of the sensor in the final application.

The device may be configured to generate interrupt signal by inertial wake-up/free-fall events as well as by the position of the device itself.

Thresholds and timing of interrupt generators are programmable by the end user on the fly.

The LIS331DLH is available in 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.
