They seem to be very similar. The value of the load resistor should probably be different though (I'd use 1Mohm) and I would connect a capacitor in parallel to the load resistor (I'd use 0.1uF or so). The provided code doesn't seem to attempt to map the measured voltage to the physical quantity the sensor is measuring, but once you get there I can help you with that. First, just verify that you're getting the measured voltage to change in reaction to the gas presence.
