Irrigation control in ahuyama crops in Sincelejo, Sucre (Colombia) managed through the Internet of Things (IoT)

Abstract

An automatic irrigation system for ahuyama crops is proposed in the department of Sucre, Colombia. The designed system is composed of a tuned proportional, integral, and derivative controller (PID) and of a data acquisition system connected to a cloud using Internet of Things tools. The user controls the crop remotely and manages the historical and in real time information to assess the water requirement of the crop according to atmospheric and soil variables. The reference values obtained from the differences between the desired humidity in the crop and the humidity measured in real time in the soil and the microclimate of the crop were lower than 2%. The system proved to be efficient, stable, and optimizes the error in steady state, which contributes to low-cost field implementation and makes the system an important contribution to the region.
