Question

What is the use of the ADXL-335 sensor?

(a) To measure acceleration

(b) To measure heat

(c) To measure temperature

(d) To measure GPS Location

I have been asked this question in an internship interview.

This is a very interesting question from ADXL335 Accelerometer Sensor topic in section Interfacing of Sensors, Actuators, and Other Modules of Arduino

Answer 1

Correct answer is (a) To measure acceleration

To explain I would say: The ADXL-335 is an accelerometer which can calculate the instantaneous acceleration. It can be used for many applications, most importantly in phones, since it can be also used for calculating the roll or tilt.
