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.
