Abstract
Objectives: This document describes an automatic irrigation system design, using SCADA software and wireless sensor network. Methods/Analysis: The system was made using the drip irrigation system method, and the communication the field and the supervisor system was established using ZigBee devices connected in mesh topology. The SCADA system monitors four variables of the field: temperature, soil moisture content, water and nutrient level and status of the ZigBee device. Findings: The purpose of this paper is not only to contribute knowledge to the development of the Colombian field, through the application of new technologies of irrigation automation of crops, but to motivate research, development and innovation around this topic. Improvements: It is contemplated the use of a web portal where you can monitor the system, thus adding a notification mode. In addition, the use of redundancy to avoid loss of data in the crop, both on the side of data acquisition, and on the side of storage. Keywords: Data Logging, Drip Irrigation, Precision Agriculture, Supervision-Control And Data Acquisition (SCADA), ZigBee
Highlights
The development of the agricultural sector is key to the future of a nation
For the Colombian case, there is a potential for growth that has been wasted, and its contribution to the Gross Domestic Product (GDP) has decreased[1], it is one of the essential activities in the economic growth that allows the development of rural areas, employment generation, poverty reduction, food security and improvement of quality of life in the countryside
The sensors to be used in the design of the wireless sensor network will be of soil temperature and humidity only, so the following criteria should be taken into account: Type: They can be active or passive: Passive sensors are low energy devices
Summary
The development of the agricultural sector is key to the future of a nation. for the Colombian case, there is a potential for growth that has been wasted, and its contribution to the Gross Domestic Product (GDP) has decreased[1], it is one of the essential activities in the economic growth that allows the development of rural areas (especially in developing countries), employment generation, poverty reduction, food security and improvement of quality of life in the countryside. It have been chosen make use of new technologies that help manage the crop using different data sources, and save time and money This is called Precision Agriculture, and it is a trend that is revolutionizing the agricultural process in the world[5]. The use of sensor networks in agriculture, in irrigation systems, could optimize the consumption of water and nutrients, through remote access to crop variables, contributing to a reduction in costs and a lower environmental impact[10]. From the practical point of view, the automation should allow an easy management of the parameters of the plant, to reduce the resistance of the farmer to the use of new technologies In this context, a supervision system (Supervision-Control And Data Acquisition (SCADA)-HMI) is essential to create the interface between farmers and field teams. An alarm recorder could be configured to inform the farmer in a timely manner about crop a nomalies, by sending email when an alarm is activated[12,13,14,15,16]
