Question

What is the minimum temperature that the LM35 Temperature Sensor Module can read?

(a) -11°C

(b) -55°C

(c) -10°C

(d) 0°C

This question was posed to me in semester exam.

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

Answer 1

Right answer is (b) -55°C

For explanation I would say: The minimum temperature that the LM35 Temperature Sensor Module can read is -55°C, below which the module cannot generate sufficiently accurate order of voltage fluctuations to denote a temperature value.
