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

Abstract

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.
