The methane concentration sensing unit generates methane concentration information based on the methane concentration of the environment and transmits it to the control circuit module 25. In detail, the type of the methane concentration sensing unit is a semiconductor gas sensor. It is mainly composed of SnO2 n-type semiconductor and heater. The sensor is equipped with a fine-hole stainless steel mesh, which has the functions of rapid heat transfer and prevention of gas explosion. The inside of the sensor adsorbs oxygen in the air during clean air, and the negative ions that form oxygen absorb the electron density in the semiconductor, thereby increasing the resistance value. When the reducing gas is adsorbed, the originally adsorbed oxygen is desorbed, and the reducing gas is adsorbed on the surface of the metal oxide semiconductor in a positive ion state. After the oxygen is removed, electrons are emitted, and the reducing gas adsorbs electrons in a positive ion state, and the electron density of the oxide semiconductor band increases. Therefore, the resistance value decreases to increase the conductivity. When restored to clean air, the metal oxide semiconductor automatically restores the negative ion adsorption of oxygen, causing the resistance value to rise to the initial state and the conductivity to recover. The sensor uses this change in electrical potential to take it out as an output voltage to detect the concentration of the gas.
