  • All MQ sensors use SnO₂ semiconductor technology with resistance varying according to gas concentration.
  • Typical detection ranges: 10 ppm to 10,000 ppm depending on the gas type.
  • Require preheating (20–60 seconds or more) for stable readings.
  • Provide analog output + digital threshold output (via comparator board).
