Interface AcceleroMeter With 8051

An accelerometer is a device that measures proper acceleration.

  • Accelerometers have multiple applications in industry and science.
  • Single and multi-axis models of accelerometer are available to detect magnitude and direction of the proper acceleration.
  • Used to sense orientation, coordinate acceleration, vibration, shock, and falling in a resistive medium.
  • Accelerometer electronic devices and video game controllers,to detect the position of the device or provide for game input.
  • So that images on screens are always displayed upright.
  • Accelerometers are available that can measure acceleration in one, two, or three orthogonal axes.
  • They are typically used in one of three modes:
    • As an intertial measurement of velocity and position,
    • As a sensor of inclination, tilt, or orientation in 2 or 3 dimensions, as referenced from the acceleration of gravity (1 g = 9.8m/s2),
    • As a vibration or impact (shock) sensor.
