Suitable for domestic or industrial on LPG (liquefied petroleum gas), butane, propane, LNG (liquefied natural gas) detection devices. It has excellent resistance to ethanol vapor, smoke interference.Tin oxide (SnO2) is a low electrical conductivity material in clean air, but with combustible gas, its conductivity increases. Using simple circuits, its changing in conductivity is changed into output signals. MQ-6 is for domestic or industrial on LPG (liquefied petroleum gas), butane, propane, LNG (liquefied natural gas) detection.
