Abstract
El presente trabajo describe el desarrollo de un nodo de medición de parámetros ambientales, específicamente, temperatura, humedad, presión atmosférica y concentración de CO2. El objetivo planteado en la ejecución del prototipo fue la construcción de un módulo embebido(nodo) de medición con conectividad WiFi, incluyendo sensores adecuados para la medición de las variables mencionadas. La alimentación se realiza a través de una fuente switching similar a la de un cargador de dispositivos móviles. El proyecto se completa con el acceso a una red IoT y la posibilidad de mostrar a través de aplicaciones web, los valores actuales y el registro temporal de las variables ambientales, obtener gráficos históricos y otros procesamientos de la información almacenada en una base de datos en la nube. Los nodos se conectan a la red WiFi de la organización. Se ha creado una máquina virtual en los servidores de la institución, en la cual se instaló un servidor MQTT. Se creó una base de datos a la cual se accede a través de aplicaciones. Se crearon dashboard para mostrar los valores en tiempo real y realizar consultas del registro histórico de las variables visualizado a través de gráficos.
This paper describes the development of a node for measuring environmental parameters, specifically, temperature, humidity, atmospheric pressure and CO2 concentration. The main objective in the design of the prototype was the construction of an embedded measurement module (node) with WiFi connectivity, including suitable sensors for the measurement of physical variables. Power is supplied through a switching power supply similar to that of a mobile device charger. The project is completed with access to an IoT network and the possibility of displaying, through web applications, the current values and the recording of environmental variables, obtaining graphs and other processing of the information stored in a database in the cloud. The nodes connect to the organization's WiFi network. A virtual machine has been created on the institution's servers, on which an MQTT server has been installed. A database was created which is accessed through applications. Dashboards were created to show the values in real time and consult the registry of the variables visualized through graphs
