The sensitive part of the gas sensor is sintered with nano SnO2 powder and an appropriate amount of catalyst doping. It is embedded with heating wire and metal electrodes. When trace amounts of methane gas appear in the air, the conductivity of the sensor will increase. The amount of change in conductivity increases with the concentration of methane gas, and the sensor can sense the methane concentration in the air by the magnitude of the conductivity change. FS01200A is a semiconductor-based methane sensor probe that is highly sensitive to polluting gases. It uses a multi-layer thick film manufacturing process to form a heater and a metal oxide semiconductor gas-sensitive layer on both sides of a miniature ceramic substrate, which are led out by electrode leads and packaged in a TO-5 metal shell.
