Description

3 Axis Digital Accelerometer – ADXL345 three-axis gravity acceleration tilt angle sensor module IIC/SPI transmission

DESCRIPTION

The ADXL345 is a small, thin, low power, 3-axis accelerometer with high resolution (13-bit) measurements at up to ± 16 g. 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.

The ADXL345 is well suited to measures the static acceleration of gravity in tilt-sensing applications, as well as dynamic acceleration resulting from motion or shock. Its high resolution (4 mg/LSB) enables measurement of inclination changes less than 1.0° .

Low power modes enable intelligent motion-based power management with threshold sensing and active acceleration measurement
