Mq9 Carbon Monoxide Methane And Lpg Gas Sensor Module Price In Pakistan

MQ-9 Carbon Monoxide, Methane and LPG Gas Sensor Module can be use to sense Carbon Monoxide and Metahane 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 other gases adsorbed under low temperature.
