ADXL345 Angle acceleration sensor

The ADXL345 is 3-axis accelerometer with high resolution  measurement at up to +/-16 g. Digital output data is  accessible through either a SPI (3 or 4 wire) or I2C digital interface. 

The ADXL345 is well suited to measure 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 

The excellent sensitivity (3.9mg/LSB 2g) provides high-precision output up to +/-16g.
