The MQ-4 natural gas sensor uses tin oxide to sense the presence of combustible gasses including propane, butane and especially methane. This semiconductor gas sensor detects the presence of methane/natural gas at concentrations from 200 ppm to 10,000 ppm, a range suitable for detecting gas leaks. Its simple, analog voltage interface requires only one analog input pin from your microcontroller.
