MQ-2 Flammable Gas and Smoke Sensor
Gas Sensor(MQ2) module is useful for gas leakage detecting(inhome and industry). It can detect LPG, i-butane, methane, alcohol, Hydrogen,somke and so on. Based on its fast response time. measurements can be taken assoon as possible. Also the sensitivity can be adjusted by the potentiometer.
MQ-2 Semiconductor Sensor for Combustible Gas
Sensitive material of MQ-2 gas sensor is SnO2, which with lowerconductivity in clean air. When the target combustible gas exist, The sensorsconductivity is more higher along with the gas concentration rising. Please usesimple electro circuit, Convert change of conductivity to correspond outputsignal of gas concentration.
MQ-2 gas sensor has high sensitivity to LPG, Propane and Hydrogen,also could be used to Methane and other combustible steam, it is with low costand suitable for different application.
