MQ-2 Flammable Gas and Smoke Sensor

MQ2 Gas Sensor is useful for gas leakage detecting(in home and industry). It can detect LPG, i-butane, methane, alcohol, Hydrogen, smoke, and so on. Based on its fast response time measurements can be taken as soon as possible. Also, the sensitivity can be adjusted by the potentiometer.

MQ2 gas sensor can detect gas concentrations anywhere from 200 to 10000ppm. MQ2 sensor is very sensitive to Propane, Hydrogen, methane, and LPG.

The MQ series of gas sensors use a small heater inside with an electrochemical sensor. They are sensitive for a range of gasses and are used indoors at room temperature.

The sensitive material of the MQ2 Gas sensor is SnO2, which has lower conductivity in clean air. When the target gas exists, the sensor’s conductivity is higher along with the gas concentration rising. MQ2 sensors could be used to detect different combustible gases especially Methane. It is very low cost and suitable for different applications. This sensor can be used to make a wireless Gas leak detector in-home security system.
