MQ9 Carbon Monoxide & Combustible Gas Sensor Module female to female Output voltage swing up toMQ9 Carbon Monoxide & Combustible Gas Sensor Module The MQ9 is a dual function gas sensor that detects both Carbon Monoxide (CO) and combustible gases like LPG and methane (CH4). It uses a SnO2 sensing element with a built in heater that operates in two alternating cycles high temperature for CO detection and low temperature for combustible gas detection. Ideal for home safety alarms, industrial monitoring, and gas leak detection systems with Arduino
