Item Asistente virtual de navegación y generación de rutas en espacios cerrados(Universidad Técnica de Ambato. Facultad de Ingeniería en Sistemas, Electrónica e Industrial. Carrera de Telecomunicaciones, 2023-03) Núñez Bonilla, Jonathan Daniel; Manzano Villafuerte, Víctor SantiagoTechnological progress and the internet of things have boosted the creation of intelligent buildings that meet the requirements of owners and managers, giving way to the collection of relevant information for the management of the place and improve the experience of visitors. One of the most attractive and at the same time challenging needs of buildings or enclosed spaces is the navigation in their interiors. To solve this demand, the use of technologies is necessary. At present there are several technologies for navigation of which stand out: UWB, Wi-Fi, Bluetooth low energy (BLE), RFID and GPS. GPS systems in outdoor environments combined with stand-alone cell phones can achieve high accuracy. However, indoors and in environments with deep shadow effects, satellite and cellular signals are often disrupted, and positioning is problematic. This project presents an indoor navigation system solution based on mobile devices using Bluetooth Low Energy (Beacons) as an enabling technology and implemented in a mobile application that suggests the most optimal route to reach a certain location with the help of a virtual assistant. The mobile application called Rutas app is developed in the Flutter framework based on Dart programming language and is available for both visitors and administrators, which presents a dynamic map of the space with information on places of interest to users and a section of routes in which depending on the place you want to reach presents the optimal route to follow, this with the help of the built-in virtual assistant, which is activated by voice. Thus, addressing problems of misplacement and improving the experience of visiting the place, it also shows the administrators reports of the places with more recurrence and users who frequent the space, this information is relevant because from it you can act and implement strategies to better manage the place.Item Sistema de monitoreo no invasivo y seguridad preventiva de factores causantes del síndrome de muerte súbita de los lactantes del Centro de Estimulación Temprana y Prenatal “Neuro Place” a través de smart textil(Universidad Técnica de Ambato. Facultad de Ingeniería en Sistemas, Electrónica e Industrial. Carrera de Telecomunicaciones, 2023-09) Lema Yungán, John David; Benalcázar Palacios, Freddy GeovannyThis project focuses on the development of an innovative Smart Textile for monitoring vital signs in infants, with the goal of preventing sudden infant death syndrome. The Smart Textile, specifically designed for the "Neuro Place" Early and Prenatal Stimulation Center, will be used by professionals at the center to monitor the infants. The project aims to provide a reliable and effective technological solution for continuous monitoring of infants' vital signs through smart fabric. During the development process of this project, the ESP32 Feather microcontroller was utilized as the central unit responsible for controlling the GY-MAX30102 sensor and the MPU-6050 sensor within the Smart Textile. The GY-MAX30102 sensor. based on photoplethysmography principles, accurately measures the infant's heart rate and blood oxygen saturation. On the other hand, the MPU-6050 sensor, equipped with an accelerometer, is used to identify and track the infant's position. Additionally, an OLED display with I2C technology was incorporated into the Smart Textile, enabling real-time visualization of the collected data. For data transmission Wi-Fi technology was employed, with the module integrated into the chosen microcontroller, to send the collected data from the microcontroller to the cloud. To facilitate interaction with the Smart Textile, a mobile application was developed using the Flutter Framework. This mobile application serves as an interface between the staff at the stimulation center and the Smart Textile allowing them to register the infant, measure vital signs, access data records, and check the battery status of the Smart Textile By utilizing the Firebase platform as the backend and developing specific scripts, the capability to send alerts to the mobile device through push notifications was enabled in case any anomalies in the infant's vital signs are detected. This ensures a prompt and efficient response to risky situations, providing the staff at the stimulation center with the opportunity to take appropriate and timely actions Finally, a reliability percentage of 98.02% was achieved for heart rate measurements. while the reliability percentage for blood oxygen saturation measurements was 98.27%. These values reflect the accuracy and dependability of the measurements conducted through the Smart Textile. The Smart Textile's battery autonomy is approximately 12.41 hours, offering ample operational time.Item Sistema electrónico para el aprendizaje de programación basada en gamificación(Universidad Técnica de Ambato. Facultad de Ingeniería en Sistemas, Electrónica e Industrial. Carrera de Telecomunicaciones, 2025-02) Eugenio Ichina Silvia Elizabeth; Castro Martin Ana PamelaTeaching programming to children is increasingly important to develop skills such as computational thinking and problem solving from an early age. However, challenges remain, such as lack of technological resources and limited teacher training in these areas. The objective of this work is the construction of an electronic prototype to teach programming to children from 7 to 11 years old. The project includes a mobile robot that uses RFID technology, receives commands through cards and provides feedback by means of sound signals through a speaker, in addition to displaying instructions on an LCD screen. The system works through movement instructions selected by children with RFID cards. The robot executes the commands instantaneously, moving within an environment of pressed cardboard blocks. The goal is to complete the path from the “start” to the “finish” tile, performing movements such as forward, backward, left and right turns, 360-degree turns, and square-shaped movements. Programming guides are presented for parents and guardians to guide children. In addition, the system allows children to program the robot autonomously, encouraging their creativity by creating customized motion sequences.Item Sistema inalámbrico de alarma comunitaria con smartwatch y tecnología IOT(Universidad Técnica de Ambato. Facultad de Ingeniería en Sistemas, Electrónica e Industrial. Carrera de Telecomunicaciones, 2025-02) Chuquitarco Taco Wilmer Fabricio; Pallo Noroña Juan PabloThe implementation of a community alarm control and monitoring system seeks to improve security in neighbourhoods and citadels, overcoming current limitations in terms of speed of response and accuracy in locating incidents. Leveraging technologies such as LoRa and advanced communication protocols such as SSE, the system optimises alert management, ensuring fast and reliable transmission. The system allows alerts to be generated via a smartwatch or a mobile app, which are transmitted using LoRa technology. The central server manages and distributes the information to both the application and the nodes, ensuring efficient communication between all elements of the system. The mobile application, with an intuitive interface, receives real-time notifications via SSE (Server Sent Events) and also provides local notifications. Each alert includes details of the user who triggered it, along with a Google Maps link that allows the user to be redirected to the location of the trigger, automatically mapping a route to the site. This system solves key problems such as delays in transmitting information and lack of accurate details about the location of the alert, significantly improving emergency response capability. Tests demonstrated instant activations, either from smartwatches or the mobile app, offering a scalable and efficient solution that can be integrated into larger projects.
