    (Universidad Técnica de Ambato. Facultad de Ingeniería en Sistemas, Electrónica e Industrial. Carrera de Ingeniería en Electrónica y Comunicaciones, 2022-09) Sasig Muso, Pedro Rodrigo; Altamirano Meléndez, Santiago
    The present research project proposes the development of a feed dispenser for trout fingerlings, this system is complemented by an artificial vision system to determine the biomass of the fingerlings and according to that information, calculate the daily food ration that the fish should eat. The dispenser and the artificial vision system are designed to be compatible with the internet of things (IOT). Therefore, the dispenser has an ESP32 for its operation. Meanwhile, the artificial vision system works with a raspberry Pi. These development boards are compatible with internet connection. This allows the artificial vision system to send the number of fingerlings it has counted, their biomass and the feeding routine to the Firebase database once it has completed its task. The dispenser takes this data and uses it to start dispersing the food according to the defined schedule. In addition, the user can control and view the parameters of the dispenser's feeding schedule through a mobile application developed in React Native or through a web platform developed in React. Feeding routine settings can be edited from both web and mobile platforms, according to user needs. The implementation of this system, it allows to contribute the field of pisciculture with a reliable feed dispenser that fulfills the task of feeding the fish and, in addition, provide additional parameters such as the number of fingerlings and their weight.

    Sistema de monitoreo para la avícola “san miguel” con una red de sensores inalámbricos basados en la tecnología LPWAN
    (Universidad Técnica de Ambato. Facultad de Ingeniería en Sistemas, Electrónica e Industrial. Carrera de Ingeniería en Electrónica y Comunicaciones, 2022-09) Orosco Tonato, Ángel Leonardo; Castro Martin, Ana Pamela
    The present research work describes the development of a monitoring system for the "San Miguel" poultry farm with a network of wireless sensors based on LPWAN technology located in the province of Cotopaxi, canton of San Miguel de Salcedo, in this way the operators of the shed of chickens will be informed at all times about the environmental conditions such as: temperature, humidity, lumens and existing CO2 concentration. The prototype monitoring system with Lora and IoT technology has 3 important elements: two slaves nodes (Node 1 and 2), one master node (Node 3), and a IoT servers for mobile devices such as computers or laptops. The Lora ESP32 microcontroller was used for the monitoring system. Node1 has 4 sensors to measure temperature, humidity, lumens, and CO2. Node 2 has 3 sensors for measuring temperature, humidity and lumens. Data collected by Node 1 and 2 is sent to Node 3. IoT server called Thinger.io receives data from Node 3, this data is shown in a user interface. An appmovil was developed with the application tool of RemoteXY cloud server to show the sensor data. Node 3 can send alarms of high temperature, low temperature and high concentration of CO2 in the environment through the use of the instant messaging system that Telegram has. The automatic alarm system brings operators an easy way to kwon if environment conditions are optimal in the poultry farm. Generally, this measurement process is carried out only with the sense of touch and based on their experience in raising chickens, therefore, having an intelligent monitoring system provides an advantage in raising chickens. The implementation of the monitoring system for the poultry farm provides better management of resources such as gas from the brooders, it also allowed identifying the concentration of CO2 in the environment to adequately ventilate the shed. In addition, the knowledge of the environmental conditions in real time and an appropriate bird care improves the quality of life of chickens.

    Sistema de control de tráfico vehicular aplicando la arquitectura Fog Computing
    (Universidad Técnica de Ambato. Facultad de Ingeniería en Sistemas, Electrónica e Industrial. Carrera de Ingeniería en Electrónica y Comunicaciones, 2021-03) Ibarra Nuñez, Edisson Miguel; Jurado Lozada, Marco Antonio
    ABSTRACT The fog computing communications architecture allows the implementation of applications that require real time data processing, such as traffic management through intelligent traffic lights, for this reason this project focuses on the design of a traffic control system vehicle for Cevallos Avenue and Eugenio Espejo Street in the city of Ambato, which allows to process the data in real time of the traffic volume and act automatically in the traffic light time intervals. The system design is based on the installation of a fog node or server in the fog for communication, storage and data processing through Wifi wireless communication technologies, 4G LTE cellular mobile phone networks, Mqtt and WebSocket communication protocols for IoT devices and a programming algorithm which allows to count vehicles using geofences or virtual perimeters to determine the appropriate traffic light phase, viewed through a real time monitoring web interface. The system also uses a mobile application designed to send the vehicle's GPS location, a server in the AWS cloud to obtain the historical records of the system and the construction of an intelligent traffic light prototype which allows to verify the operation of the traffic light phases. Finally, the technical parameters that fog has with respect to cloud computing are compared, obtaining advantages in fog computing since it has low latency and greater processing capacity.

    (Universidad Técnica de Ambato. Facultad de Ingeniería en Sistemas, Electrónica e Industrial. Carrera de Ingeniería en Electrónica y Comunicaciones, 2021-03) Garcés Salazar, Roberto Andrés; Manzano Villafuerte, Víctor Santiago
    ABSTRACT The current pandemic has hampered medical care and access to the various conventional health services, which can sometimes be difficult for people living far from the nearest health service, or they cannot be mobilized due to various medical conditions. This project implements a telemedicine system with a home-focused architecture using IoT based on four elements: User interface, administration, connectivity, and medical sensors. In the user interface layer, an application was developed with the React-Native framework for the Android TV system, which will receive the sensing data from the medical sensor layer of the BPMs and SpO2 MAX30100 sensor via Bluetooth, embedded within a wearable electronic circuit. This data will be sent via the TCP/IP protocol and managed via Odoo, hosted in an Amazon EC2 instance. The stored information can be displayed through tables and graphs, alert the user when receiving abnormal data, and send prescriptions to the Android TV app in a timely manner. A survey of forty health professionals was carried out to ascertain the benefit of the proposed system. Of this sample, 88.5 percent would be willing to implement the system at their workplace. In addition, I should mention that this work is part of the research project "Telemedicine System for the Monitoring of Vital Signals in a Smart TV Environment", approved by Resolution No. UTA- CONIN-2020-0297-R.
