com MQ-4 Semiconductor Sensor for Natural Gas Sensitive material of MQ-4 gas sensor is SnO2, which with lower conductivity in clean air.
When the target combustible gas exist, The sensor’s conductivity is more higher along with the gas concentration rising.
Please use simple electrocircuit, Convert change of conductivity to correspond output signal of gas concentration.
MQ-4 gas sensor has high sensitity to Methane, also to Propane and Butane.
The sensor could be used to detect different combustible gas, especially Methane, it is with low cost and suitable for different application.
Character * Good sensitivity to Combustible gas in wide ran...
