MQ-5 LPG gas sensor module

MQ-5 LPG gas sensor, CH4 Sensor, and C3H8 Gas Sensor with long lifespan and low price for domestic gas leakage alarm. The sensitive material of the MQ-5 gas sensor is SnO2, which has lower conductivity in clean air. When the target flammable gas exist, the sensor’s conductivity gets higher along with the gas concentration rising. Users can convert the change of conductivity to correspond to the output signal of gas concentration through a simple circuit. The MQ-5 gas sensor has high sensitivity to butane, propane, methane and can detect methane and propane at the same time. It also can detect kinds of flammable gases, especially LPG(propane).It is a kind of low-cost sensor for many applications.
Detection Gas: Propane, Methane
Detection Range: 300～10000ppm（CH4,C3H8）
Application: domestic gas leakage alarm, portable gas detector
