The ADXL345 is a small, thin, ultra-low power 3-axis accelerometer with high resolution (13 bits) and a measurement range of ±16g. The digital output data is 16-bit two's complement format, which can be accessed through SPI (3-wire or 4-wire) or IIC digital interface;

The ADXL345 is suitable for mobile device applications. It can measure static gravitational acceleration in tilt detection applications, as well as dynamic acceleration due to motion or shock. It has high resolution (4mg/LSB) and is capable of measuring tilt changes of 0.25°. Using the ADXL345 digital output acceleration eliminates the need for digital-to-analog conversion, saving system cost and board area.
