Can the MQ2 Gas Sensor differentiate between two different gases with the same PPM?

Can the MQ2 Gas Sensor differentiate between two different gases with the same PPM? Correct Answer No

The MQ2 Gas Sensor is not designed to tell which gases are present in the air surrounding the module. It can only tell what is the concentration or PPM value of a gas. The nature or name of the gas has to be known beforehand while using this sensor.

Statement (I): To use a sensor, we generally need to add signal conditioning circuitry, such as circuits which amplify and convert from analog to digital, to get the sensor signal in the right form, take account of any non-linearities, and calibrate it. Statement (II): A smart sensor is integrated with the required buffering and conditioning circuitry in a single element and provides functions beyond that of just a sensor.
