Gravity: Analog Gas Sensor (MQ2) SF_Wireless and IoT Antennas so we've put together aThis is a generic Arduino gas sensor. It has MQ2 probe which is able to detect LPG, i butane, propane, methane, alcohol, Hydrogen, smoke. It can be used in gas leakage detecting device in consumer and industry markets. It has a high sensitivity and fast response time. 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
