Consider the following actions:

  1. 1.Detection of car crash/collision which results in the deployment of airbags almost instantaneously
  2. 2.Detection of accidental free fall of a laptop towards the ground which results in the immediate turning off of the hard drive.
  3. 3.Detection of the tilt of the smartphone which results in the rotation of display between portrait and landscape mode

How many of the above actions is the function of the accelerometer required?

  1. A.Only one
  2. B.Only two
  3. C.All three
  4. D.None
▶ Answer & Explanation

Correct answer: C. All three

Accelerometers are motion-sensing devices that measure acceleration, including the force of gravity. They can detect changes in velocity and orientation. In vehicles, they are crucial for sensing impacts to trigger airbag deployment. Laptops use them to detect falls and protect the hard drive. Smartphones utilize them to sense device orientation and adjust the display accordingly.
