      Features:

      MQ-2 gas sensor sensitive material used in the clean air low conductivity tin oxide (SnO2). When there is the environment in which the combustible gas sensor is, the conductivity sensor with increasing concentration of combustible gases in the air increases. Using a simple circuit to convert the change in conductivity of the gas concentration corresponding to the output signal. MQ-2 gas sensors high on gas, propane, hydrogen sensitivity of detection of natural gas and other flammable vapors are also very good. This sensor can detect a variety of flammable gas and is a low-cost sensor for a variety of applications.

      Gas may be used in homes and factories as leakage monitoring devices suitable for the detection of gas, butane, propane, methane, smoke, etc.
