MQ-7 Carbon Monoxide Gas Sensor Insulation Tape and 8 of which areThis 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
