Gravity: Analog CH4 Gas Sensor (MQ4) For Arduino Shipping:4-6 Days com/datasheets/BreakoutBoards/SparkFun_Beefy_3_v10This is an Arduino CH4 gas sensor. It uses MQ4 probe which is able to detect natural gas, CH4. It is less sensitivity in detecting alcohol, cooking fumes, and cigarette smoke. The sensitivity can be adjusted by the potentiometer. The output is proportional to the density of gas. You can use analog reading to read the data from this sensor. To ease the difficulty of using this sensor, a Gravity Interface is adapted to allow plug&play. The Arduino IO
