Wine has a long history and strong cultural heritage in China, and the wine cellar is used for fermentation and long-term storage in the winemaking process. Because the wine cellar is relatively closed and the alcohol is flammable and volatile, the construction and design of the wine cellar requires a temperature and humidity sensor in order to control the temperature and humidity. It is also necessary to ensure that ventilation is provided in a timely manner to avoid the formation of an explosive mixture due to excessive alcohol concentration in the air. It is necessary to maintain constant temperature and humidity conditions in the wine cellar to maintain the quality of the wine during fermentation and storage. However, this is precisely the contradiction with ventilation. Once the alcohol content in the air reaches 3.3% or more due to poor ventilation of the wine cellar, it will explode when exposed to sparks. Especially when a damage leak occurs, the concentration of alcohol in the air rises rapidly. On the other hand, too high a concentration of alcohol in the air may also pose a choking hazard to the person in it. In order to prevent accidents, the flammable gas sensor is used to monitor the alcohol content in the wine cellar, so that the air concentration is below the minimum explosion concentration range to ensure the safety of the person entering the wine cellar. The measuring principle of the combustible gas sensor of the sensor expert network is that the platinum wire is wound into a spring shape, and the aluminum oxide ceramic is coated thereon, and finally the catalytic material is added and fired together to form a stable structure, so that Catalytic element. In contrast, compensation components that do not draw catalytic materials are mainly used to compensate for changes in the gas environment. Usually, the catalytic element and the compensation element are used in pairs and connected by means of a Wheatstone bridge. When there is no flammable gas in the environment, the catalytic element and the compensating element in the bridge will not react, so the circuit is in equilibrium and there is no output. When a combustible gas is present, the bridge is no longer balanced due to the oxidation reaction of the catalytic element, and the output of the circuit will be related to factors such as the rate of the combustion reaction.
