Accelerometer

1. Which of the following features rely on accelerometer being calibrated?

• Movement detection

• Green driving

• Over speeding

2. What is a threshold?

3. What are the main advantages of using Continuous auto calibration mode?

4. How can auto-calibration be initiated?

• SMS command

• Automatically once calibration reaches certain threshold

• Both are correct
