The ADXL345 is a 3-axis MEMS accelerometer with high resolution (13-bit) measurement at up to +-16 g that is small, thin, and low-power. Digital output data is 16-bit twos complement and can be accessed via an SPI (3- or 4-wire) or I2C digital interface. The ADXL345 is well suited to measuring static gravity acceleration in tilt-sensing applications, as well as dynamic acceleration caused by motion or shock. Its high resolution (4 mg/LSB) allows it to measure inclination changes of less than 1.0 degrees.
