MQ-4 Methane Gas Sensor

Sensitive material of MQ-4 gas sensor is SnO2, which with lower conductivity in clean air. When the target combustible gas exist, The sensors 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 Natural gas, Methane, and could be used to detect both Methane and Propane. The sensor could be used to detect different combustible gas especially Methane, it is with low cost and suitable for different application.

Features:

• High sensitivity to Combustible gas in wide range
• High sensitivity to Natural gas?Methane?Coal gas?CO etc gas
• Fast response
• Wide detection range
• Stable performance, long life,low cost     
• Simple drive circuit

Application:

• Domestic gas leakage detector
• Industrial Combustible gas detector
• Portable gas detector
• Gas leak alarm, Gas detector
