The MQ-9 Analog Gas Sensor has high sensitivity to Carbon Monoxide, Methane and LPG. The sensor can be used to detect different gases containing CO and combustible gases, it is low-cost and suitable for a variety of applications. The core sensing material of the MQ-9 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). The sensor conductivity is higher along with the gas concentration. When the temperature rises (heated by 5.0V), it detects Methane, Propane, combustible gas, etc and cleans the other gases adsorbed under low temperatures.
