Implementación de sistema de lectura de variables con sensores utilizando sistemas embebidos en IoT.

Abstract

The development of a system for reading variables with sensors using embedded systems in IoT, will use the ESP-WROOM-32 microcontroller integrating different home automation sensors in a small electronic card. Regarding its firmware, this microcontroller will host a web page developed in HTML, CSS and Javascript code; this result is applied in the form of embedded HTML hosted in the device's memory space, in addition to this, the ESP32 will capture the sensor measurements to show the results in indicators contained in the web page. With integrated wifi communication, it will use the WebServer and WebSocket protocols for the management of multiple local clients and real-time communication for the visualization of the information obtained. Due to the properties of CSS, the page has the particularity of having a responsive design, so its visualization adjusts to smaller screens such as cell phones or tablets from the web browser. With the implementation of this IoT monitoring system, it is expected to be an educational tool with practical applications for students of technical courses at the Faculty of Technical Education for Development of the UCSG, since the proposed electronic module allows the use of GPIOS not used in the present integration work.
