What it does

The MQ2 Gas Sensor for Arduino/Raspberry Pi is a reliable gas detection module ideal for Arduino and Raspberry Pi projects. It detects LPG, propane, methane, hydrogen, smoke, and other combustible gases with both analog and digital outputs.

Key features

  • Wide gas detection range covering LPG, propane, methane, hydrogen, smoke
  • Dual output – analog and digital for flexible interfacing
  • Adjustable sensitivity via onboard potentiometer
  • Fast response time for rapid gas detection
  • Long lifespan with stable performance
  • 5V operation compatible with all microcontrollers
  • Digital comparator with adjustable threshold

Good to know

  • Requires 20-48 hours initial burn-in for accurate readings
  • Sensitive to temperature and humidity changes
  • For indoor use in well-ventilated environments
  • Calibrate in clean air before deployment
  • Not suitable for precise quantitative measurement
