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.
