Description
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 range
High sensitivity to Natural gas
Long life and low cost
Simple drive circuit
Application:
Domestic gas leakage detector
Industrial Combustible gas detector
Portable gas detector
