Hello readers welcome to new post. Today we will discuss Introduction to LIS3DH Triple-Axis Accelerometer. It is high power high performance three axis linear acceleratormeter and created by STMicroelectronics that is part of nano group and has compatibility to digital I2C/SPI interface standard output.
It uses less power and considered as the part of latest battery operations. In this post we will discuss its working and some other parameters. So let get started.
Introduction to LIS3DH Triple-Axis Accelerometer
- The LIS3DH is three axis linear accelerometer comes with I2C or SPI interfacing. Its lower power consuming features helps to use it in different high level operations and embedded system.
- It comes with user friendly scales ±2g/±4g/±8g/±16g and has ability to measure acceleration through output data rate of one hertz to 5.3 KHz
- Its self test features helps to monitor its function ability in different applications.
- It can be configured to make interrupts signals through use of two inertial wake/free fall modules through device positioning.
- Thresholds and timing of interrupts generators get programmed through end user at fly.
- The LIS3DH integrated through 32-level first in, FIFO buffer permitting users to store data that helps to retard the intervention by the host processor.
- The LIS3DH is comes in small thin plastic land grid array packing and its temperature range is -40 °C to +85 °C
LIS3DH Triple-Axis Accelerometer Features
