Desenvolvimento de protótipo para determinação da sensação térmica em tempo real e sua aplicação em áreas distintas na cidade de Fortaleza-CE

Abstract

One of the major challenges in the urban centers development is the guarantee of environmental quality. The irregular occupation of these areas, combined with the anthropic activities pollution and the absence of green areas, can generate environments that are thermally uncomfortable for the human being. Considering the relevance of this issue, as it involves the well-being of man and the balance of the natural environment, one of the steps to propose solutions and improvements is to know the problem through studies and data collection. The current work proposes the construction of a prototype to collect values of wind speeds, temperature and relative air humidity, in order to determine the thermal sensation in real time, through the IDT and TEv indices. The prototype is basically constituted by electronic components, having as its main element a microcontroller, responsible for the management of the devices that composes the prototype. It was replicated, totalizing into three prototypes, where its elements went through calibration procedures, based on a Davis weather station. A pilot application was carried out to evaluate the prototypes operation in different locations in the city of Fortaleza (CE). The prototypes presented good functionality and reduced cost, around R$ 170 reais each, compared to commercial equipment, where the value can reach R$ 7500 reais per equipment. As to its application, it can be observed particularities in each sampling site, which through the indices used, revealed conditions of discomfort for the population.
