    Sistema inteligente de monitoreo y vigilancia para plantaciones agrícolas de pitahaya en el cantón Palora basado en tecnologías IoT y LoRa

    The Internet of Things (IoT) focused on smart agriculture has made it possible to achieve great technological development in this sector through the development and implementation of a smart agriculture system for pitahaya plantations in the Palora canton, which will be installed to allow that pitahaya farmers have intelligent monitoring and proper management of their crops based on data from humidity sensors, soil pH level, C02, light and temperature. The main objective of this research work is the monitoring of soil variables in pitahaya plantations, taking data directly from the soil through two nodes that are bidirectional each one, they are composed of different stages. The first stage is the data acquisition in which an Arduino Uno was obtained to acquire the plantation information, then the node transmits this information through LoRa to a Gateway called the gateway stage, then the data they are sent to an internet connection device where the data is managed and printed through POST methods to the database managed with MySQL, finally for the design of the monitoring application, web development technologies such as HTML, PHP as backend were developed. , JavaScript and CSS. In addition, one of the nodes controls the irrigation of the plantation through a tank level sensor and solenoid valves that open or close, depending on the activity to be carried out. The sensors cover an approximate area of 10,000 square meters. The implementation of the monitoring system allowed the improvement and control of the soil through adequate monitoring at all times and in real time of the plantations, in addition the implementation of LoRa demonstrated to have a low-power and longrange wireless technology with the objective of identifying and reduce costs, improving pitahaya production and soil management.

    Pulsera electrónica inalámbrica con tecnología LoRa para la monitorización de turistas en parques nacionales
    (Universidad Técnica de Ambato. Facultad de Ingeniería en Sistemas, Electrónica e Industrial. Carrera de Ingeniería en Electrónica y Comunicaciones, 2022-03) Guerrero Aguilar, Juan Carlos; Pallo, Juan Pablo
    This research work details the development of a wireless electronic bracelet for monitoring tourists in National Parks using LoRa technology to have a long range in data transmission, its performance tests were carried out in Ambato in the Huachi Chico neighborhood. , in the Cotopaxi National Park and the Sangay National Park. The tourist monitoring system in National Parks consists of a WSN or wireless sensor network, which is divided into the wireless node, the gateway and the base station. The wireless node consists of the bracelet that is responsible for collecting the data from the heart rate sensor and the blood oxygen level, which are located on the tourist's wrist using the electronic bracelet, the data is also acquired of the GPS through the Neo 6m module, which sends the information with the NMEA protocol by serial communication to the microcontroller and through some processes the information of the latitude, longitude, altitude, speed and satellites is extracted. Once the necessary data has been taken, it is sent through LoRa communication to the gateway. The gateway receives the data and sends it through a file created in Python to a database where there will be a track and history of the tourist's location. Finally, the tourist data is displayed through an interface made in Grafana which was installed on a raspberry Pi 4, this being the base station. For monitoring, it is done every 5 seconds and a local map server was developed which can represent the tourist's location on a map without the need for an internet connection, this was achieved through requests to the server's database. made in a php file, and later send the data in Json format so that it can be represented on the map from which the images were downloaded using Mobile Atlas. The electronic bracelet underwent some functional tests taking into account the National Park and the time of your visit.
