ADXL345 Digital Accelerometer IC. This  is a high resolution (13-bit) measurement at up to ±16 g. Digital output data is formatted as 16-bit two’s complement. It is  accessible through either a SPI (3- or 4-wire) or I2C digital interface. The ADXL345 is well suited for small hand held or mobile device.

ADXL345 Digital Accelerometer IC measures the static acceleration of gravity. In tilt-sensing applications and dynamic acceleration resulting from motion or shock. Its high resolution (4 mg/LSB) enables measurement of inclination changes very little as 0.25o Several special sensing functions are provided. Activity and inactivity sensing detect the presence or lack of motion and if the acceleration on any axis exceeds a user-set level. Tap sensing detects single and double taps. Free-fall sensing detects if the device is falling. These functions can be mapped to one of two interrupt output pins. An integrated, 32-level first in, first out (FIFO) buffer can be used to store data to minimize host processor intervention.

Low power modes enable intelligent motion-based power management with threshold sensing and active acceleration measurement at extremely low power dissipation.
Package dimension is 3  X 5  X 1 mm, 14 lead LGA
Supply Voltage: 1.8 to 3.6V
