Development of an Electrical circuit with Arduino implementation to automate a Peltier Thermoelectric cooling system

Abstract

The emergence of refrigerators marked a significant technological evolution by extending the preservation of perishable goods, a pursuit that dates back to times prior to the 20th century. Driven by technological advancements, this area of notable impact on human progress strives to create automated devices to integrate daily activities, satisfying fundamental needs. In this context, the present work aims at a comprehensive understanding of automated systems and the application of concepts such as electricity, heat transfer, and Peltier cooling technology. The core of this project lies in the development of a deep understanding of automated systems, with an emphasis on constructing an automated cooling system. This system utilizes an Arduino board as a central component, playing the pivotal role of regulating and controlling the cooling process. The ability for timely shutdown, as determined by the user, constitutes a key element, minimizing component wear and, consequently, extending the system's lifespan. The project's execution required analytical calculations to underpin prototype development. The Arduino board, in conjunction with Peltier cooling technology, resulted in an automated cooling system, providing proper preservation of temperature-sensitive products. In summary, the research illustrates the trajectory of refrigeration systems' evolution from their invention to the current era, where automation and technological integration are predominant factors. The study underscores the importance of understanding automated systems, electricity, and cooling technologies, demonstrating their practical application in constructing a functional prototype aligned with contemporary needs for preservation and energy efficiency.
