 ====Reading the Data:====
-The MQ-2 sensor functions as a voltage divider. The analog voltage output varies accordingly with the  concentration of combustible gasses and its interaction with the oxygen, thus yielding  a higher voltage proportional to the quantity of the present  gas. The sensor cannot determine which gas is present, however the interaction with any of the possible measurable gasses creates a distinct pattern that has been provided by the manufacturers, shown in Figure #. By creating a code that follows the guidelines set by the manufacturer design we can then measure with a small margin of error, the concentration of distinct types of gasses in the air simply by analyzing the resistance ratio  of the sensor (RS/R0).
