Dispositivo para controle Inteligente de reservatórios de água e sistemas de Irrigação via aplicativo mobile

Abstract

Water scarcity is a growing challenge across the world. Several research sources indicate that in the coming years a significant portion of the world’s population may be subject to water scarcity. This is due to a combination of factors, including climate change, deforestation, increased demand caused by population growth, urbanization and especially inadequate management of water resources. The potential for home automation to mitigate this problem is increasingly in focus. Through the use of technology and the Internet of Things (IoT), it is possible to optimize the use of water in homes, contributing to its economy, having a better management of this resource and consequently a greater longevity of it for the next generations. With automation systems it is possible to control and monitor the use of water in real time. They can identify consumption patterns, limit the flow of water in showers and faucets, set a scheduled time for a certain task, all to ensure that water is only used when and where it is needed. For example, automatic sprinklers can be programmed to water gardens during the driest times of the day, they can be automatically turned off when it rains or even be programmed to only turn on for a certain period. Another option is for water control in reservoirs, in which it is possible to determine how much water should be in a given reservoir with the aid of flow sensors, for example, or what is the maximum limit of a reservoir with a level sensor, indicating which can only add water up to a certain point, avoiding water overflow and consequently waste. All these points define the objective of the work, to combine the world shortage problem with home automation through a low cost device. With the prototype developed, it will be possible to apply it to different situations, two examples of which have already been mentioned, automation in irrigation of plantations and control of water in reservoirs. With it, through an application on the phone and a WiFi connection, it will be possible to determine various parameters of use such as the volume to be used, for how long a pump/electrovalve should be turned on at a given time or a simple manual activation all through the radio frequency communication. In addition to viewing various information in real time, such as flow in l/min, total volume, whether or not the reservoir limit has been reached and the current status of a pump, for example. This work will describe all the theoretical basis of the prototype, the development methodology as well as the performance of the prototype in the tests carried out.
