ADXL345 Tripple Axis Accelerometer Board

The ADXL345 Triple Axis Accelerometer Board is a small, thin, low-power, 3-axis accelerometer that offers high-resolution (13-bit) measurements up to ±16g. Its digital output data is formatted as a 16-bit two’s complement and can be accessed via either an SPI (3- or 4-wire) or I2C digital interface.

The ADXL345 is ideal for mobile device applications. It can measure the static acceleration of gravity for tilt-sensing applications and dynamic acceleration from motion or shock. With a high resolution of 4 mg/LSB, it can detect inclination changes of less than 1.0°.

This accelerometer includes several special sensing functions:

• Activity and inactivity sensing to detect motion or lack thereof, based on a user-set acceleration threshold.
• Tap sensing to detect single and double taps.
• Free-fall sensing to detect if the device is falling.

These functions can be assigned to one of two interrupt output pins. Additionally, the ADXL345 features an integrated, patent-pending 32-level first-in, first-out (FIFO) buffer to store data, minimizing the need for host processor intervention.

Low power modes enable intelligent motion-based power management, incorporating threshold sensing and active acceleration measurement with very low power consumption.

Applications:

• Pointing devices
• Handsets
• Medical instrumentation
• Gaming
• Industrial instrumentation
• Personal navigation devices
• Hard disk drive (HDD) protection
• Fitness equipment
• Defense and aerospace
