The ADXL345 is a small, thin, ultra-low power 3-axis accelerometer with high resolution (13 bits) and measurement range of ± 16g. The digital output data is in 16-bit twos complement format and is accessible via SPI (3-wire or 4-wire) or I2C digital interface. Its high resolution (3.9 mg / LSB) enables measurement of tilt angle changes of less than 1.0 °
