Sistema electrónico de monitoreo y control de captación de energía solar y electromagnética para aplicaciones IoT

Abstract

This work shows the design and implementation of a monitoring system for a hybrid energy harvesting device based on the Internet of Things (IoT), with the purpose of collecting data in real time in order to be visualized in a metrics representation platform using Cloud Computing; which is formed by a server or several servers that involve software and hardware whose purpose is to monitor and control energy harvesting systems. For the project we used open-source tools selected on the basis of a technical study, the results of which were verified with the implementation of a dashboard. The monitored voltage signals are processed by the ADS1115 of 16 bits that allows greater accuracy in reading the values that are sent to the central controller ESP32, which is responsible for reading the processed data and transmit them via the MQTT protocol to the Red Hat Enterprice Linux server located in the Microsoft Azure cloud, and then be observed in Grafana. In this sense, when working with wireless technology, cloud services and IoT devices in the collection and monitoring of data in real time, it is noted that the operation of the system is efficient, with voltage measurements with a maximum peak of 22.5V in the day and 0V at night by the panel and 200 mV by the antenna, so as long as there are good weather conditions, the period of time in which there is greater energy uptake is from 11:00 am to 16:00 pm. Finally, the reliability of the developed device is higher than 90%, being an alternative system that meets the measurement requirements in relation to other monitoring devices.
