MQ-9 Gas Sensor Module For Carbon Monoxide, Methane, and LPG Detector Module Multimeters it is ideal for bothMQ 9 Gas Sensor Module This is MQ 9 Carbon Monoxide, Methane, and LPG Gas Sensor Module can be used to sense Carbon Monoxide and Methane Gas. The sensitive material of the MQ 9 gas sensor is SnO2, which with lower conductivity in clean air. It makes detection by the method of cycle high and low temperature, and detect CO when the low temperature (heated by 1. 5V). The sensors conductivity is higher along with the gas concentration rising. The MQ9 Gas
