Beschreibung MQ7 Gas Sensor has high sensitity to Coal gas and could be used to detect different combustible gas in wide range. When the target combustible gas exists, the conductivity of this sensor is much higher along with the gas concentration rising. It is suitable for many different applications, can be used as domestic gas leakage detector and industrial combustible gas detector. The gas sensor has a stable performance, fast response time and simple drive circuit, but a low cost.
