Abstract：Energy carbon emision monitoring is an important part of China's carbon peak and carbon neutrality goals，but China is stillfacing the problem of obtaining energy carbon emissondataquicklyand accurately.Therefore，this study proposed the use of hydrothermallysynthesized CuS as a gas-sensitive material to fabricate CO 2 monitoring sensors with varying synthesis temperatures，aiming to enhance CO2 capture efficiency. Additionally，variational mode decomposition （VMD） was employed to improve the anti-interference capability of the CO2 monitoring sensors.The experimental results showed that the response time of the sensor synthesis temperature of 200‰ was lower than that of the synthesis temperature of and 170% ，and the higher the synthesis temperature of the sensor was conducive to the crystalizationof CuS materials andthe adsorption ofcarbon dioxide.At a synthesis temperature of 200 C ，the CuS sensor had the lowest detection limit，which can capture the carbon dioxide emitted by theenergy industry in time and provide technical support for rapid carbon emission monitoring.Withthe increaseof the signal-to-noise ratio，thedata recognitionaccuracyof the variational mode and the deep learning algorithm decreased，and when the signal-to-noise ratio was 10dB ，the accuracy of the carbon emission data recognition of the variational mode was as high as 97.8% .Therefore，the variational mode can effectively improve the anti-interference performance of the CO2 monitoring sensor.
