MQ-2 датчик газа бутана метана дыма обнаружения моделирование модуля серии МК комплект ~ MQ-135 9

The gas-sensitive material used by the mq-2 gas sensor is SnO2, which is less conductive in clean air.When combustible gas exists in the environment of the sensor, the conductivity of the sensor increases with the increase of combustible gas concentration in the air.A simple circuit is used to convert the change in conductivity into an output signal corresponding to the gas concentration.Mq-2 gas sensor is highly sensitive to liquefied gas, propane and hydrogen, and is also ideal for the detection of natural gas and other combustible steam.The sensor can detect a variety of combustible gases and is a low-cost sensor for a variety of applications
