Henan Hanwei Electronics Co., Ltd www.hwsensor.com MQ-9 Semiconductor Sensor for CO, Combustible Gas Sensitive material of MQ-9 gas sensor is SnO2, which with lower conductivity in clean air. It make detection by method of cycle high and low temperature, and detect CO when low temperature (heated by 1.5V). The sensor’s conductivity is more higher along with the gas concentration rising. When high temperature (heated by 5.0V), it detects Methane, Propane etc combustible gas and cleans the ot
