Description
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.

Applications:
ADXL345 is very suitable for mobile applications. It can be applied to the skew detection in the measurement of the static acceleration of gravity, also can measure the movement or impact caused by the dynamic acceleration. The high resolution ( 4mg / LSB ), can be measured is less than 1.0° Angle change. Applications like:
- HDD shock protection
- Vibration sensor
- Game controller input
- Robotics
- Smart vehicles
- Anywhere you need to obtain motion-sensing & orientation information.
