Aplicações da Placa Peltier para Desenvolvimento de Projetos de Feiras de Ciências

Abstract

This work presents a study on the applications of the Peltier plate controlled by the ESP32 microcontroller board in the development of projects for Science Fairs. The Peltier plate, also known as a thermoelectric plate, is a semiconductor device that allows temperature control through the Peltier effect. The research was conducted with the aim of investigating the possibilities and limitations of using this technology in scientific projects presented at school fairs. The initial literature review covered the operating principles of the Peltier plate, exploring the physical concepts governing the thermoelectric effect, the versatility of the ESP32 microcontroller board, and methods for creating educational material. In addition, previous works that employed these technologies in various areas such as electronics, refrigeration, automation, and energy were analyzed.This review showed that the Peltier plate is a versatile tool with the potential for various applications. After conducting studies on the Peltier plate, various efficiency tests were carried out. The results obtained, the assembly methods of the experimental apparatus, and the justifications for the assembly and the results are presented in the chapters, highlighting the potential for temperature monitoring and remote control of the plate. However, it was not possible to achieve temperatures close to zero degrees Celsius, as was one of the initial objectives. Thus, this limitation, found in the present work, has the potential to become the subject of future research.
