MQ-9 Gas Sensor Module Plastic Bevel Gear 32 Teeth Fixed CodeThis MQ 9 gas sensor is very sensitive to carbon monoxide, methane and LPG. The sensitive material of the MQ 9 gas sensor is SnO2, which has a lower conductivity in clean air. It detects high and low temperature alternations and detects CO at low temperature (heated to 1. 5V). The conductivity of the sensor increases as the gas concentration increases. As the temperature rises (heated to 5. 0 V), it detects methane, propane, combustible gas, etc. and
