Abstract
Resumen: Luego de 2 años de confinamiento por la pandemia causada por el COVID-19, para el retorno a clases presenciales la Universidad Católica Boliviana San Pablo sede Cochabamba desarrolló un sistema de desinfección portátil empleando luz UV- C que emplea un sensor de movimiento PIR, el cual está conectado a la placa de desarrollo ESP32 que controla dos módulos relé: uno de estado sólido que enciende y apaga la lámpara y otro electromecánico que controla una cerradura eléctrica mientras el proceso de desinfección esté activo. Para tener un seguimiento en tiempo real, se integra un bot en la aplicación Telegram. La placa ESP32 se conecta a Internet a través de la red WiFi. Se tiene un servidor configurado en la nube por medio del proveedor AWS. Dentro del mismo, se implementa un servidor Mosquitto, que es el broker del protocolo de comunicación MQTT para trabajar con la herramienta de desarrollo Node-RED e integrar una interfaz gráfica capaz de controlar el sistema de forma remota y desde cualquier parte del mundo. Se realizaron pruebas en diferentes ambientes de la universidad; la validación del sistema y de la desinfección se la hizo a través de papeles fotosensibles que varían su tonalidad según la incidencia de luz UV-C que tengan y con el análisis de superficies en un laboratorio clínico. Ambos métodos validaron la funcionalidad del sistema.
Abstract: After 2 years of confinement due to the pandemic caused by COVID-19, for the return to face-to-face classes, the Universidad Católica Boliviana San Pablo Sede Cochabamba developed a portable disinfection system using UV-C light that uses a PIR movement sensor, the which is connected to the ESP32 development board that controls two relay modules: a solid state one that turns the lamp on and off and another electromechanical one that controls an electric lock while the disinfection process is active. To have real-time monitoring, a bot is integrated into the Telegram application. The ESP32 board connects to the Internet through WiFi. There is a server configured in the cloud through the AWS provider. Within it, a Mosquitto server is implemented, which is the MQTT communication protocol broker to work with the Node-RED development tool and integrate a graphical interface capable of controlling the system remotely and from anywhere in the world. Tests were carried out in different environments of the university; The validation of the system and the disinfection was done through photosensitive papers that vary their hue according to the incidence of UV-C light they have and with the analysis of surfaces in a clinical laboratory. Both methods validated the functionality of the system.
