Desenvolvimento de um sistema de irrigação e monitoria do campo agrícola com base em internet of things (IoT) caso de estudo: Associação Regantes da Massaca - Distrito de Boane

Abstract

Agriculture plays a vital role in Mozambique's development, as this is where much of its economic potential lies. Despite all the socio-economic expression and potential of the segment, agricultural activity constantly faces the challenge of increasing food production on a regular basis, being affected by some basic problems, among them the difficulty of using water and the lack of adequate technological alternatives to the living conditions of these farmers who, because of this, are prevented from producing more and better throughout the year.The present work aims to develop an intelligent and sustainable automation model for irrigation and monitoring of agricultural land based on the Internet of Things and low-cost automation. The first step that was taken was to try to describe and understand the data necessary for the implementation of an irrigation system so that later, these serve as a guide for the construction of an automated irrigation system and low cost compared to irrigation systems existing. In this work, the main benefits of an irrigation system and monitoring of the agricultural field based on IoT were also identified, which are: sustainability, productivity, economy, improvement of product quality, workforce; The model and prototype developed and tested in the field allow us to conclude that, in addition to the functional success, the system had to be relatively low cost compared to current systems, in order to guide the research, it was questioned whether the proposed system could be more affordable in terms of irrigation systems implemented Associação Regantes da Massaca - District of Boane. With the budget obtained and applying a tolerance value of 10% of the total value, referring to price fluctuations and hidden costs, a total cost of 319,088.00MT is obtained for the implementation of the automated system, where it can also be concluded that the IoT-based irrigation and field monitoring system is less expensive by a minimum margin of 2% and with a maximum margin of 62%, for this comparison, the costs related to the maintenance of the systems due to lack of data that indicate the performance of the systems as well as their life cycle. For future work, some modifications can be made, such as the use of LoRaWAN technology (wide area and long-range network), use of WebSockets that facilitate the transmission of messages from different devices, use of the water flow sensor to measure water consumption used by the plantation.
