MQ-7 Gas Sensor Module For Carbon Monoxide Detector Module Switches 5-inch touchscreen LCD for RaspberryMQ 7 Gas Sensor Module The MQ 7 gas sensor module is a device that can detect the presence of carbon monoxide (CO) gas in the air. It is commonly used in applications such as gas leak detectors, safety devices, and industrial control systems. The MQ 7 sensor operates by using a chemical reaction between the CO gas and a conductive metal oxide to produce a current. The magnitude of the current is proportional to the concentration of CO gas in the air.
