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