ADXL345 Tripple Axis Accelerometer Board
ADXL345 Tripple Axis Accelerometer Board is a small, thin, low-power,3-axis accelerometer with a high resolution (13-bit) measurement at up to ±16 g. Digital output data is formatted as a 16-bit two’s complement and is accessible through either an SPI (3- or 4-wire) or I2C digital interface. These functions can be mapped to one of two interrupt output pins. An integrated, patent-pending 32-level first-in, first-out (FIFO) buffer can be used to store data to minimize host processor intervention.

Specification
Description
The ADXL345 Tripple Axis Accelerometer Board is well suited for mobile device applications. It measures the static acceleration of gravity in tilt-sensing applications, as well as dynamic acceleration resulting from motion or shock. Its high resolution (4 mg/LSB) enables measurement of inclination changes less than 1.0°. This Low power modes enable intelligent motion-based power management with threshold sensing and active acceleration measurement at extremely low power dissipation.ADXL345 Tripple Axis Accelerometer Board is a small, thin, low-power,3-axis accelerometer with a high resolution (13-bit) measurement at up to ±16 g.

- The device offers a variety of special detection features.
- Active and Inactive Detection Detects the presence or absence of motion by comparing the acceleration on any axis with a user-set threshold.
- Percussion detection function can detect any direction of single vibration and double vibration action.
- It can measure changes in the inclination angle of about 0.25°.
