Implementación de un sistema electrónico de monitoreo y control en tiempo real para el riego en cultivos de cacao.

Abstract

The present research aimed to implement an electronic system for monitoring and real-time control for irrigation in cocoa crops. From the bibliographic review of cocoa crops, the percentage of humidity was known. The electronic system was designed based on two nodes mobile and independent sensors which carried out the monitoring of climatic variables such as: temperature, soil moisture and radiation, as well as a control node in charge of the opening and closing of the solenoid valves based on the information provided by the sensor nodes for the respective irrigation, this node operates in manual and automatic mode, stores the information in a memory microSD, displays the information received in real time by the sensor nodes through a screen LCD, and requires an external switch to start the motor pump. The communication between the nodes is wireless through the use of LoRa technology. The implementation was carried at “Emmanuel” farm located in Bucay canton, where based on evidence, it was determined that the electronic system has a 34% reduction in irrigation time compared to Traditional mechanical system used, having a greater saving of water resources. Some tests were conducted to determine that wireless communication is maintained over a distance of lossless transmission and reception of 320 meters, stability was demonstrated in sensor nodes which makes them reliable and applicable, turning the electronic system into a tool to maintain a technical control regarding irrigation. It is recommended to extend the test times of the electronic system to have better results and broaden the study to increase the data collection capacity.
