Diseño de prototipo iot basado en la placa nodemcu esp32 para controlar y medir el distanciamiento social en la fis-epn.

Abstract

The COVID-19 pandemic has presented a global challenge for humanity, and social distancing has become the primary preventive measure to avoid virus spread. In this work, we propose the design of an IoT prototype solution to control and measure social distancing at the Faculty of Systems Engineering at the Escuela Politécnica Nacional. The prototype utilizes IoT devices that measure the distance between them using RSSI signals and alert users with a sound alarm when they get closer than 1.5 meters. The collected data is sent to a database, which can be viewed through a web portal so that users can see their contact record. The Scrum project developer was used to develop the solution, which allowed mitigating unexpected changes in the design of the IoT prototype. The solution was successfully tested with unit tests using the jest.js framework, as well as top-down and down-top integration tests. A system usability survey was carried out, which obtained a score of 85/100, indicating that the vast majority of users find the prototype solution useful and easy to use. In future works, miniaturization processes could be carried out to reduce energy expenditure and construction costs. The implementation of noise reduction algorithms is also recommended to refine the process of calculating distances between devices and improve the accuracy and reliability of the solution.
