This abstract describes the development of a thermal model applied to a radiosonde system that calculates the average temperature on the printed circuit board PCB of the system. A radiosonde  is a device that allows the study of various physical parameters in the lower atmosphere, and transmits the results to ground through an RF link. It is also essential that the electronic circuitsof the system are properly insulated. Using the thermal physics module called "Conjugated Heat Transfer" of the COMSOL utility, simulations are performed which allow modeling the  atmospheric conditions of the environment that the radiosonde will be exposed. Based on this analysis, materials and geometry are chosen for a proper thermal insulation which will allow the correct operation of electronic circuits of the system.
