Payment Methods:

The MQ-4 Methane & Natural Gas Sensor Module detects methane, CNG, and other combustible gases in the surrounding air using a heated tin dioxide sensing element. It is well suited to gas leak alarms, air-quality monitors, and other safety projects that need to flag a rising concentration of flammable gas.

Key features:

  • Methane/CNG Detection: Sensitive to methane, natural gas, and other combustible gases in the 300 to 10000 ppm range.
  • Analog and Digital Output: Delivers a proportional analog voltage plus an adjustable digital trigger for alarm circuits.
  • Onboard Sensitivity Trimmer: Potentiometer sets the digital output threshold to match the application.
  • Fast Response and Recovery: Quick reaction to changing gas concentration for real-time monitoring.
  • Simple 4-Pin Interface: VCC, GND, analog, and digital output pins for easy microcontroller wiring.
  • Status LED: Onboard power indicator confirms the module is energized.
