MQ-XX Sensor series is a sensitive gas detection sensor which provide a lower conductivity in a clean air. When the sensor detect a gas exist in area the sensor conductivity will increase. These sensor has a high sensitivity to Ozone, LPG, C3H8, CO, H, C2H6O and C6H6 gas detection. MQ sensor series are useful in domestic, industrial, portable gas detection and automotive. Please refer to diagram and datasheets below for further information and characteristics on each model of MQ sensor.
