The sensor can be used to detect different gases containing CO and combustible gases, it is low cost and suitable for different applications. Â Sensitive material of MQ9 gas sensor is SnO2, which has a lower conductivity in clean air. It makes detection by cycling high and low temperature, and detects CO when low temperature heated by 1.5V.
