**MQ4 Gas Sensor Module** is a metal oxide semiconductor (MOS) type gas sensor that is mainly used to detect the concentration of methane (CNG) gas in the air. It is typically used in homes or factories to detect the concentration of methane gas. The sensor is composed of a micro-ceramic tube of AL2O3, a sensitive layer of tin dioxide, a measuring electrode, and a heater that is fixed into a crust made of plastic and stainless steel net. The sensor requires a power supply and can output an analog voltage between 0.1-0.3V based on the intensity of the gas. The detection concentration of the sensor is between 200-10000ppm (natural gas/methane). The sensor has a TTL-compatible input and output and operates at 5V.
