 MQ-2 sensitive material is used for gas sensors in clean air low conductivity tin oxide (SnO 2 ) . When there is the environment in the combustible gas sensor, conductivity sensor with increasing concentrations of combustible gases in air increases. Using a simple circuit to convert the change in conductivity of the gas concentration corresponding to the output signal.

MQ-2 gas sensor high on liquefied petroleum gas, propane, hydrogen sensitivity, detection of natural gas and other flammable vapors are also very good. This sensor can detect a variety of flammable gas, is a low-cost sensors for a variety of applications.
