Accelerometer

  • Accelerometers are used to determine the orientation of the drone in flight.

  • Accelerometer measures the proper acceleration.

  • Accelerometer values help determine the roll and pitch movements of the drone.

  • Accelerometer measures the change in the acceleration due to gravity along X axis (forward and backward) or along the Y axis(sideward).

  • The accelerometer uses the above data to calculate roll and pitch of the drone.

  • One type of technology senses the micro movement of very small structures embedded in a small integrated circuit.

  • The movement of these small ‘diving boards’ changes the amount of electrical current moving through the structure, indicating a change of position relative to gravity.

  • Another technology used in accelerometers is thermal sensing, which offers several distinct advantages.
