Abstract：This paper analyzes the experimental data of temperature sensor monitoring related meteorological factors in different environments,and finds out the environmental impact factors that have a great influence on the measurement results of temperature sensor.Using the LSSVM optimal algorithm of the least squares support vector machine(LSSVM) with better fitting results,the error of measurement results of temperature sensors under laboratory conditions and outdoor conditions is analyzed and simulated through mathematical modeling.Under the premise of verifying the model and using the general steps of uncertainty analysis,the temperature and humidity sensor measurement results are assessed as Class A uncertainty,Class B uncertainty,synthesis uncertainty,and extension uncertainty.Finally,the measurement results of temperature sensor are evaluated comprehensively.Through this study,a reference for determining the uncertainty of meteorological senser measurement is provided.
