MQ-3 Gas Sensor (Alcohol Detection)

The MQ-3 Gas Sensor is optimized for detecting alcohol vapors (ethanol). It is commonly used in breath analyzers and alcohol detection systems. The sensor provides high sensitivity to alcohol while maintaining low sensitivity to other gases, ensuring accurate readings in applications requiring selective detection.

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).
