Item Estudio de los niveles de radiación electromagnética en la Facultad de Ingeniería en Sistemas, Electrónica e Industrial(Universidad Técnica de Ambato. Facultad de Ingeniería en Sistemas, Electrónica e Industrial. Carrera de Telecomunicaciones, 2024-08) Valverde Sánchez, Edwin David; Cuji Rodríguez, Julio EnriqueThe development of technology, together with the constant increase in energy consumption, generates the need to evaluate and storage of this energy from the environment. There is not much research on how to capture and efficiently use this energy. To measure the non-ionizing radiation in the FISEI campus, recurrent and sporadic nodes were determined in which a measurement of the immission electric field was taken in a wide band between 50 MHz and 3.5 GHz during 6 minutes in the morning, half day and afternoon during a period of 4 weeks using PCE EM 29 instruments. Finally, the data is transferred to ArcGIS to create a radiation diagram using the kernel interpolation method. Nodes with high electric field level were identified in Agora (0.665 V/m), Hall E (0.568 V/m), Garden 1 (0.427 V/m) and Car Park (0.389 V/m). The radiation diagrams show that the areas near the Access Points exhibit elevated levels of electromagnetic radiation. However, these levels do not exceed safe limits according to ARCOTEL regulations. Energy harvesting tests show that areas with higher radiation generate significant voltage gains (0.307 V), demonstrating higher energy harvesting efficiency compared to areas with lower radiation.Item Sistema de almacenamiento para aplicación en sistemas de energy harvesting(Universidad Técnica de Ambato. Facultad de Ingeniería en Sistemas, Electrónica e Industrial. Carrera de Electrónica y Comunicaciones, 2023-09) Gallardo Cherrez, Cristina Guadalupe; Salazar Escobar, Fabian RodrigoThe impact of the IoT (Internet of Things) market has been increasing and its main objective is automation and efficiency. However, for the use of the sensors and peripheral devices they must work with batteries or wired to a power source or electrical installation: Thanks to Energy Harvesting, energy from the environment can be used to power these low-consumption devices. Energy Harvesting is considered one of the revolutions of sustainable energy since its process of capturing energy is through the environment or nearby environment and converting it into electrical energy. [1]. The project will be carried out from the results obtained in energy capture systems previously developed by students of the Technical University of Ambato where it is intended to obtain parameters such as: voltage, charge-discharge time and the current that intervene in the storage systems, optimal for Energy Harvesting systems, the objective is to carry out tests on the Energy Harvesting system with different storage systems to improve the collection and storage of energy. For the project, data has been taken by monitoring the batteries together with the INA219 module, which allows reporting voltage and current, acquiring in real time. resulting in the charging and discharging of each storage system that were taken in a period of time between 90min to 4 hours resulting in supercapacitors. lithium ion and lithium polymer batteries can collect 0.3[mV], 0.2[mV] and 0.23[mV] in 90min respectively. After analyzing the results. it is concluded that supercapacitors are optimal for implementation in Energy Harvesting systems because energy is stored as an electric field, unlike batteries that store it as chemical potential, which causes a chemical reaction that reduces the battery life: This project is part of the research: "Capture of Clean Low Power Energy for Powering Fifth Generation Devices (5G)", approved by Resolution No. UTA-CONIN-2022-0015-R dated February 2, 2022Item Rectenna basada en arreglos de antenas tipo parche para captación de energía electromagnética(Universidad Técnica de Ambato. Facultad de Ingeniería en Sistemas, Electrónica e Industrial. Carrera de Ingeniería en Electrónica y Comunicaciones, 2023-09) Tello Matehus, Fausto David; Gordón Gallegos, Carlos Diegot present, most of the energy sources are natural gas, oil and nuclear industry. But it has to be taken into account that these sources of energy supply are not for life and their price is generally accepted. In addition, it must be considered that they are environmentally unfriendly. Thus, today there is a need for energy alternatives that address the shortcomings that other resources have, considering all the studies that have been conducted on the collection of cleaner, greener and safer energy. Through various researches it is known that energy has many resources from where it can be obtained, such as solar energy, wind energy, vibrations and the one that in this intention will be investigated, which is electromagnetic environmental signals. This research project is focused on gathering information on rectennas, as well as on patch antenna arrays for Energy Harvesting Systems designed at frequencies up to 3 Ghz, in addition to a simulation and implementation of a rectenna consisting of elements and technology suitable for electromagnetic energy harvesting systems; and at the same time analyze the results obtained from the tests carried out in order to demonstrate its efficiency in the aforementioned systems. The design of this prototype, was made in Ansys HFSS software, which allowed us to make a 2x2 array of rectangular patch antennas, in which λ/4 transformers are used to couple the transmission lines to a characteristic impedance of 50 Ohms; at the same time the design of a multiplier and voltage rectifier for high frequencies is also performed, in this case for 2. 4 Ghz; in such a way that by joining the antenna array with the rectifier, a useful rectenna for electromagnetic energy collection is obtained.Item Indumentaria electrónica orientada al monitoreo del ritmo cardíaco en deportistas basado e Energy Harvesting.(Universidad Técnica de Ambato. Facultad de Ingeniería en Sistemas, Electrónica e Industrial. Carrera de Telecomunicaciones, 2023-03) Veloz Jaya, Alexis Israel; Manzano Villafuerte, SantiagoThis project shows the design and implementation of an electronic textile for continuous heart rate monitoring based on energy harvesting, divided into a sweater that incorporates the heart rate sensor along with the flexible solar panel for energy collection and a removable module that allows the display and sending of data. For the continuous measurement of beats per minute (bpm), the MAX30102 sensor was used, which uses the photoplethysmography method to detect the heart's pulsations based on the light reflected from the blood circulating in the blood vessels. These measurements are displayed on an oled display, located in the removable module on the chest, allowing easy viewing of data by the athlete. For data processing, the Arduino Lilypad USB microcontroller is used whose supply voltage can vary between 3.3 V and 5.5 V, for power supply to the microcontroller a flexible solar panel was used, which has a maximum output voltage of 7.9 V, this voltage is rectified by the MP1584EN reducer module whose output was adjusted so that when the solar panel delivers the maximum voltage of 7.9 V the module delivers a maximum of 5.35 V. To keep track of the data, they are sent to a database in Firebase, for which a SIM800L module using GSM/GPRS wireless technology was used. The sending of alerts for exceeding the maximum heart rate threshold is done by push notifications to the mobile device through the application developed for Android, which also allows access to the data log and to consult the connection and battery status of the clothing. Finally, bpm measurements are 98%, which is within the ANSI/AAMI EC13 standard, which establishes a percentage of up to ± 10% or ± 5bpm error. The solar panel allows up to 6 hours of energy autonomy for the electronic clothing on a sunny day and 5 hours on a cloudy day.Item Sistema electrónico de monitoreo y control de captación de energía solar y electromagnética para aplicaciones IoT(Universidad Técnica de Ambato. Facultad de Ingeniería en Sistemas, Electrónica e Industrial. Carrera de Telecomunicaciones, 2022-09) Teneda Ardila, Santiago Efraín; Córdova Córdova, Edgar PatricioThis 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.Item Sistema electrónico de monitoreo y control de captación de energía solar y electromagnética para aplicaciones IoT(Universidad Técnica de Ambato.
