Accordingly, the microcontroller xxx excites the humidity sensitive resistor xxx by applying an alternating pulse, such as a 5 volt pulse, to pins xxx and xxx, such that pin xxx is "high" (i.e., at 5 V) for a period of time and pin xxx is "low" (i.e., 0 V), then pin xxx is "high" for a period of time and pin xxx is low.
As a result, the average excitation voltage to the humidity sensitive resistor xxx is zero.
During the time period when pin xxx is "high", the microcontroller xxx senses the humidity of the gas by determining if the tap voltage pin xxx is a logic "zero" or a logic "one."
