The ADXL345 series 3-axis Digital Accelerometer with high resolution 13-bit measurement at up to ±16g. Digital output data is formatted as 16-bit twos complement and is accessible through either a SPI 3- or 4-wire or I²C digital interface. It measures the static acceleration of gravity in tilt-sensing applications, as well as dynamic acceleration resulting from motion or shock. Its high resolution 3.9mg/LSB enables measurement of inclination changes less than 1.0°. Several special sensing functions are provided. Activity and inactivity sensing detect the presence or lack of motion by comparing the acceleration on any axis with user-set thresholds. An integrated memory management system with a 32-level first in, first out FIFO buffer can be used to store data to minimize host processor activity and lower overall system power consumption.
