MQ-4 Methane Gas Sensor Natural Coal Co methane detector module for Arduino

Product 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.

Feature:

• 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
