Does one need to calibrate the LM35 Temperature Sensor Module?

A. Yes

B. No

This question was posed to me in an online interview.

This interesting question is from LM35 Temperature Sensor Module in chapter Interfacing of Sensors, Actuators, and Other Modules of Arduino

The correct choice is B. No

The explanation: There is no need to calibrate the LM35 Temperature Sensor Module since it is already pre-calibrated precisely to the degrees centigrade scale and this is absolute and cannot be changed after the time of manufacture.
