Question

What is the use of the LM35 Temperature Sensor Module?

(a) Object Identification

(b) To provide 3G Connectivity

(c) To measure temperature

(d) To measure Wi-Fi strength

I have been asked this question by my school principal while I was bunking the class.

My enquiry is from LM35 Temperature Sensor Module in division Interfacing of Sensors, Actuators, and Other Modules of Arduino

Answer 1

The correct answer is (c) To measure temperature

Easy explanation: The LM35 Temperature sensor module is used for measuring the temperature in the immediate surroundings of the sensor. The output of the sensor is an analog voltage which is proportional to the Celsius temperature scale.
