Embodiment Construction
[0045] Embodiments of the present invention are described in detail below, and the embodiments described with reference to the drawings are exemplary, and embodiments of the present invention are described in detail below.
[0046] In related technologies, the methods for monitoring gas concentration are only optimized based on the functional relationship between the change of the baseline signal of the electrochemical sensor and the temperature and humidity of the environment. The algorithm is complex and similar to a black box operation, and it is difficult for users to intervene in the optimization process. process; it does not understand and explain the baseline drift caused by temperature and humidity from the real physical laws, and the obtained parameterization scheme cannot really be explained by physical laws; and its essence is to construct and train related Algorithm model, the obtained algorithm has locality, and in many cases, it cannot be generalized to the new me...

Description
technical field [0001] The invention relates to the technical field of atmospheric monitoring, in particular to a device for monitoring gas concentration, a sensor for monitoring gas concentration and a method for monitoring gas concentration. Background technique [0002] Accurately measuring the concentration of air pollutants and accurately delineating the distribution of air pollutants with ultra-high temporal and spatial resolutions are increasingly becoming the focus of research on air pollution prevention and control, such as pollution source location and emission characteristics monitoring, air quality improvement, and population health effects caused by air pollutant exposure. main direction of work. [0003] To achieve the above monitoring goals, miniaturized gas sensors, such as metal oxide semiconductor sensors and electrochemical sensors, must be used. However, for small gas sensors such as electrochemical sensors, they are generally used for monitoring air pol...
