(a) To rotate the screen

(b) To protect hard drives from damage

(c) To get the angle on monitor

(d) To get the linear acceleration

This question was posed to me by my school teacher while I was bunking the class.

My question is taken from Accelerometer and Gyroscope Sensor in division Sensors of IOT

Answer 1

The correct option is (b) To protect hard drives from damage

The best explanation: Accelerometer in laptops protect hard drives from damage. If the laptop were to suddenly drop while in use, the accelerometer would detect the sudden free fall and immediately turn off the hard drive to avoid hitting the reading heads into the hard drive platter.
