“Diseño y desarrollo de una plataforma prototipo para visualización, control y comunicación con Raspberry Pi en ambientes IoT”

Abstract

The objective of this technical project is to design and develop a prototype platform for visualization, control and communication with Raspberry Pi in IoT (Internet of Things) environments. To develop the platform, the V Model methodology was used or also known as the Four Level Model, the Nuxt.js framework was used, which is based on Vue.js for the front-end and Node.js for the back-end, the pattern The design I work with is MVVM (Model View-View Model) since it is the same one used by the framework. The platform is designed to send and receive data in the form of messages, its client is the Raspberry Pi. The client receives digital signals from the devices (sensors, actuators and controllers) through the GPIOs (general purpose input / output). The user generates a script that fulfills specific functions for MQTT, such as connection, subscription and publication, indicating the number of GPIOs that send or receive the signal. It is in charge of sending messages to the platform. MQTT is a lightweight and flexible protocol that communicates to the broker through messages. The EMQX broker manages customer data, receives published data and decides who should receive it, makes communication between hardware and software possible in real time.
