MQ-5 Gas Sensor
If you want to detect different types of gases, you will need sensors.
If you need any data on the sensitive material then, the Waveshare MQ-5 is a quite good solution.
The MQ5 ( MQ-5 ) is used in gas leakage detecting equipment in consumer and industry applications, this sensor is suitable for detecting LPG, natural gas, coal gas.
Avoid the noise of alcohol, cooking fumes, and cigarette smoke.
The sensitivity can be adjusted by the potentiometer.
The sensitive material of the MQ-5 gas sensor is SnO2, which with lower conductivity in clean air.
When the target combustible gas exists, The sensor’s conductivity is higher along with the gas concentration rising.
Please use a simple electro circuit, Convert the change of conductivity to the corresponding output signal of gas concentration.
MQ-5 gas sensor has a high sensitivity to LPG, LNG, Natural gas, iso-butane, propane, Town gas, 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
