More info

This module is perfectly compatible with Arduino boards and can detect several type of elements:

  • Smoke
  • methane
  • alcohol
  • Hydrogen
  • propane
  • i-butane
  • LPG

It has 2 outputs.

  • 1 Analog output. the output voltage varies depending on the gaz concentration.
  • 1 TTl digital output, you can adjust the sensitivity level with a small potentiometer at the back of the module. You will need to adjust the threshold of the module for it to trigger at the desired gaz/smoke level.

Note: This component might require a separate 5V power supply because some arduino board voltage regulator might not deliver enough current for it.

For more details, the MQ2 sensor datasheet is provided at the bottom of this page.
