The MQ-5 is a gas sensor module designed to detect the presence of flammable gases in the air. It is commonly used in gas leakage detection systems and various safety applications where the detection of combustible gases is critical.
This sensor module is part of the MQ series of gas sensors, which are manufactured by Winsen and are widely used for gas detection purposes.
MQ-5 Semiconductor Sensor for Combustible Gas Sensitive material of MQ-5 gas sensor is SnO2, which with lower conductivity in clean air. When the target combustible gas exist, The sensor’s conductivity is more higher along with the gas concentration rising. Please use simple electrocircuit, Convert change of conductivity to correspond output signal of gas concentration. The gas sensor has high sensitity to Methane, Propane and Butane, and could be used to detect both Methane and Propane. The sensor could be used to detect different combustible gas especially Methane, it is with low cost and suitable for different application.
1. High sensitivity to LPG, natural gas , town gas
2. Small sensitivity to alcohol, smoke.
3. Fast response.
4. Stable and long life
5. Simple drive circuit
They are used in gas leakage detecting equipments in family and industry, are suitable for detecting of LPG, natural gas , town gas, avoid the noise of alcohol and cooking fumes and cigarette smoke.
