How to Use the ADXL345 Accelerometer Module

ADXL345 Accelerometer module consists of 8 pins. Using the ADXL345 module with a microcontroller is very easy. Connect VCC and GND pins to 5V and GND pins of Microcontroller. Also, connect SCL and SDA pins to the SCL and SDA pins of Arduino.

The basic structure of the accelerometer consists of fixed plates and moving plates. When the acceleration is applied on an axis capacitance between fixed plates and moving plates is changed. This results in a sensor output voltage amplitude, which is proportional to the acceleration.

Applications of ADXL345 Accelerometer

  • Cost-sensitive, low power, motion- and tilt-sensing applications
  • Mobile devices
  • Gaming systems
  • Disk drive protection
  • Image stabilization
  • Sports and health devices
