Item Sistema de telemetría para el control y monitoreo del consumo de agua en entornos residenciales basado en la arquitectura de Red Lorawan(Universidad Técnica de Ambato. Facultad de Ingeniería en Sistemas, Electrónica e Industrial. Carrera de Ingeniería en Electrónica y Comunicaciones, 2024-08) Saigua Uchuari, Sofia Elizabeth; Altamirano Meléndez, Santiago MauricioThe implementation of the Internet of Things (IoT) increasingly addresses more fields in which it is possible to have control and monitoring of variables such as water flow, which gives a plus and bringing the digital era to another level where society is increasingly benefited. This research project shows how a novel telemetry system has been developed and implemented for the control and consumption of drinking water in residences, based on Low Power Wide Area Networks (LPWAN, in short, as it will be used hereinafter), which therefore uses a communication protocol and network architecture, with which it is possible to make communication links between IoT devices. This prototype was implemented in two residences located in Venezuela and Casimiro Nieto streets in Canton Rumiñahui. The system consists of an end node, gateway or concentrator, network server and application server; The final nodes or final devices are the sensors installed in each residence that measure the water flow, these measurements have been tested and calibrated together with the measurements emitted by the analog meters and performing a mathematical operation based on the data obtained from the water sheets in cubic meters, These data are then sent through the LoRaWAN architecture to a Gateway, data that are sent to the server using a bidirectional and light MQTT messaging protocol and then displayed on the Node-Red dashboard, where the water consumption graphs are shown in real time. The system establishes communication with the MySQL database hosted on Google Cloud Platform with which management and monitoring is possible.Item Sistema automatizado de control y monitoreo basado en tecnología Lorawan y MQTT para el cultivo de hortalizas bajo invernadero(Universidad Técnica de Ambato. Facultad de Ingeniería en Sistemas, Electrónica e Industrial. Carrera de Ingeniería en Electrónica y Comunicaciones, 2023-03) Pérez Reyes, Freddy Josué; Sánchez Zumba, Andrea PatriciaThe continuous progress of technology and the application of the Internet of Things (IoT) in the agricultural sector has allowed an advance in the systems that favor the development of crops. This project develops a control and monitoring system for the cultivation of vegetables under greenhouse in the Huachi Grande parish of Ambato. The objective is to provide the grower with an autonomous system capable of making intelligent decisions without the need for constant supervision by a person. The system allows monitoring and control of temperature and humidity, as well as pH levels and the amount of radiation that the plants receive during the day, and also has an artificial lighting system. The purpose of this research work is to provide a favorable environment for cultivation inside a greenhouse, for this we work with temperature and humidity sensors, soil moisture sensors, pH sensor and solar radiation sensor. In order to control the temperature inside the greenhouse, two fans and an automatic curtain closing and opening system by means of a low-speed electric motor are used, as well as soil humidity control, which is carried out by means of drip irrigation. On the other hand, for pH monitoring, a sensor is used for the water that enters the crop through the irrigation hoses. Finally, a solar radiation sensor is used to monitor the amount of radiation received by the plants, in order to activate artificial lighting, if necessary, with the objective of increasing the period of time during which the plant performs photosynthesis. The technology used is based on LoRaWAN and the MQTT protocol. The system has two Lora nodes and a gateway to communicate with the server and connect the system to the Internet. To control the system, an HMI based on Node-RED is used, which allows constant real-time monitoring, automatic or manual control of the system and visualization of daily statistics. In addition, the system has a control and monitoring through the Telegram application, through which the producer receives alert notifications and can control the system manually.Item Sistema electrónico de localización y monitorización para el seguimiento de turistas en el volcán Chimborazo.(Universidad Técnica de Ambato. Facultad de Ingeniería en Sistemas, Electrónica e Industrial. Carrera de Ingeniería en Electrónica y Comunicaciones, 2023-02) Endara Vejar, Cynthia Jessenia; Miño Romero, Fabián Santiago; Salazar Logroño, Franklin WilfridoAt present, many people worldwide practice mountaineering. Andinists are always at risk of accidents, when such incidents occur at high altitudes or in remote areas, search and rescue operations are not always successful. It presents some difficulty in locating tourists on the Chimborazo volcano because there’s no precedent for the implementation of some kind of immediate location system and data monitoring. Consequently, in the present titling project, an electronic system for the location and monitoring of tourists in the Chimborazo volcano is implemented. To achieve this objective, a low-cost electronic kit was developed in order to track tourists using modules and digital sensors, as well as an emergency system in case of possible accidents. The collected information is transmitted to a server which will be hosted in cloud hosting, allowing remote monitoring through a web interface. Thus achieving a record of both the position in real time and previous dates. Allowing the authorities, rescuers and tourist guides to act quickly in the face of a possible risk situationItem Asistente electrónico de agricultura hidropónica aplicando Machine Learning(Universidad Técnica de Ambato.

Facultad de Ingeniería en Sistemas, Electrónica e Industrial. Carrera de Ingeniería en Electrónica y Comunicaciones, 2022-09) Oñate Zuñiga, Elvis Rolando; Pallo Noroña, Juan PabloDamage to electronic equipment and household appliances commonly occurs due to prolonged or recurring overexposure to surges in the electrical supply, producing monetary loss for people. This research project describes the development of a remote management system for protection against residential electrical surges, based on hardware and free software. The device has current and voltage sensors, which allow to measure the voltage and current in AC. When the sensors detect a sudden increase in voltage and/or current, as well as a decrease in voltage below 10% of the nominal voltage, the ESP32 controller board will automatically cut off the electrical power supply to the residence as a measure of protection against overvoltage, undervoltage or current surges; For this, a solid-state relay capable of withstanding a load current of up to 200 A is used. To monitor the voltage and current values that the device is marking remotely from anywhere in the world, an Android mobile application was developed using the Flutter development framework. The data is read by the MQTT Broker application located on the Amazon Web Services cloud computing platform under the Amazon ECS container service. The voltage and current data are sent to this Broker from the device through a SIM800L module, which uses GPRS technology. The use of GPRS was considered the best option to avoid incidents related to communications, since there is no dependence on any type of hub or router.Item Prototipo de un sistema de supervisión agrícola para factores ambientales(Universidad Técnica de Ambato.
