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
