What is the formula for obtaining the temperature value in degrees centigrade from the LM35 Temperature Sensor while using an ADC?

(a) °C=ADC/10mV

(b) °C=ADC/100mV

(c) °C=ADC/1mV

(d) °C=ADC/120mV

I have been asked this question in a national level competition.

My question is based upon LM35 Temperature Sensor Module in chapter Interfacing of Sensors, Actuators, and Other Modules of Arduino

Best answer
Correct choice is (a) °C=ADC/10mV

The best explanation: The correct formula for converting the voltage reading taken from the ADC into the correct degrees centigrade value of the temperature surrounding the sensor is °C=ADC/10mV. This is because 10mV is the scale factor of the LM35 Temperature Sensor Module.
