The 7Semi ADXL345 breakout board utilises the ADXL345 chip designed by Analog Devices is a 3-Axis, +-2 g/+-4 g/+-8 g/+-16 g Digital Accelerometer. The ADXL345 is a small, thin, low power, 3-axis accelerometer with high resolution (13-bit) measurement at up to +-16g. Digital output data is formatted as 16-bit twos complement and is accessible through either a SPI (3- or 4-wire) or I2C digital interface.

The ADXL345 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.

Several special sensing functions are provided. Activity and inactivity sensing detect the presence or lack of motion and if the acceleration on any axis exceeds a user-set level. Tap sensing detects single and double taps. Free-fall sensing detects if the device is falling. 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.

Low power modes enable intelligent motion-based power management with threshold sensing and active acceleration measurement at extremely low power dissipation.

Key Features
  • Single tap/double tap detection
  • Activity/inactivity monitoring
  • Free-fall detection
  • Supply voltage : 3.3V/5V
  • Ultralow power: as low as 23 uA in measurement mode and 0.1 uA in standby mode at VS = 2.5 V (typical)
  • SPI (3- and 4-wire) and I2C digital interfaces
  • Dimensions: 32.5 x 22 mm

Triple Axis Digital Accelerometer: A Triple Axis Digital Accelerometer is a type of accelerometer that measures acceleration in three dimensions and provides digital output. It uses a microelectromechanical system (MEMS) to detect changes in acceleration and converts them into digital signals, which can be read by a microcontroller or other digital device. These accelerometers can be configured to measure acceleration along the X, Y, and Z axes separately or in combination. They are commonly used in applications such as gaming controllers, smartphones, fitness trackers, and drones. Compared to analog accelerometers, digital accelerometers offer higher accuracy, stability, and sensitivity. They also come with additional features such as built-in self-tests, power management, and programmable interrupt capabilities. Triple Axis Digital Accelerometers are becoming increasingly popular due to their ease of use, reliability, and versatility.
