MQ-7 Carbon Monoxide Gas Sensor Insulation Tape Common (COM)This MQ7 Gas Sensor is another MQ Gas Sensors family Metal Oxide Semiconductor (MOS) type Gas Sensor. Its primary Applications is to detect carbon monoxide. This sensor has a sensing element that is mostly aluminium oxide based ceramic that has been coated with Tin dioxide (SnO2) and is enclosed in a stainless steel mesh. When CO gas comes into contact with the sensing element, the element's resistivity changes. The difference is then measured to
