ADXL345 Accelerometer

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 ° Low-power mode supports motion-based intelligent power management for threshold sensing and motion acceleration measurement with very low power consumption. The ADXL345 is perfect for mobile device applications. It measures static gravitational acceleration in tilt detection applications as well as dynamic acceleration due to motion or impact.
