MQ-5 is a highly sensitive gas sensor which is capable of detecting liquefied gas, methane, propane, butane, and other combustible gases in the air.
MQ-5 gas sensor module is very useful for gas leak detector, other industrial combustible gas detector and gas monitoring devices to be used at home.
It has excellent resistance to ethanol and other smoke interference.
