    The 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.

    At 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 situation

    Sistema domótico para personas con capacidad limitada de movimiento en la extremidad superior derecha utilizando reconocimiento de gestos de la mano y algoritmos de Machine Learning
    (Universidad Técnica de Ambato. Facultad de Ingeniería en Sistemas, Electrónica e Industrial. Carrera de Ingeniería en Sistemas Computacionales e Informáticos, 2022-09) Martinez Velasco, Ronnie Julian; Nogales Portero, Rubén Eduardo
    People with physical disabilities (PD) have problems carrying out daily activities, affecting their independence. In this context, a person with PD can communicate through hand gestures or facial gestures, among others. However, selecting the features and patterns that separate one gesture from another is not a trivial problem. In this sense, a real-time domotic system (DS) that works with three subsystems is proposed. The first subsystem recognizes hand gestures using a machine learning model and infrared information. The machine learning model consists of preprocessing, feature extraction, classification, and postprocessing modules. The second subsystem relays the message between the subsystems. Finally, the third subsystem activates the operation of the actuators by gestures. The HGR model was trained using 6720 observations and tested offline with 1680 observations, giving an accuracy rate of 92.759%. additionally, the DS was tested online with 1500 observations from 10 users whose persons were not part of the input dataset or model testing. Online testing gives an accuracy rate of 84.07%. Once the hand gesture is recognized, it is sent wireless to an Esp8266 board through the MQTT protocol. The Esp8266 board activates the operation of several actuators. The mosquitto broker embedded in a raspberry pi manages the sending and receiving of messages between the computer where the gesture is recognized and the Esp8266 board. The theoretical response time of the DS is 118.87 ms.
