Mq-x series are all kinds of strange gas detectors, gas, natural gas, lighter leakage can be detected, alcohol, formaldehyde, inhalable suspension can be detected.

TypeGasDetecting range
MQ-2Smoke, liquefied gas, butane, propane, methane, alcohol, hydrogen300-10000ppm
MQ-2BCombustible gas300-10000ppm
MQ-3Alcohol, ethanol 
MQ-4Methane, natural gas 
MQ-5Liquefied gas, natural gas, gas300-5000ppm
MQ-6Butane, propane, LNG, LPG 
MQ-7Carbon monoxide10-1000ppm
MQ-8hydrogen 
MQ-135Air quality (concentration of CO2, alcohol, benzene, NOx, ammonia, etc.) 


Note that mq-135 can detect all the gases listed above, but cannot distinguish them. If you want to target one gas specifically, it is best to choose another sensor. The sensor also requires a heater to warm up the sensor. It is not recommended to use it with a smaller battery, as it will quickly run out of battery power.

Parameters:
Working voltage: 3.3V
Output type: digital signal, analog signal
Interface mode: ph2.0-4p
Module size: 34 x 25mm
Module weight: About 80g
