Application of the Internet of Things to Optimize Water Rationing in a Small Residence Anderson Lopes de Oliveira, Maicon Batista Farias da Silva

Abstract

This article aims to study a solution to minimize the waste of water of a residence, once this water resource is limited and its rationing is essential so that we can use it in the future without its lack. The water rationing will be based on statistical data collected through a set of devices, using the concept of Internet of Things (IOT). Through a flow sensor installed after the residence hydrometer, data will be collected and sent to a system where will be processed and its information sent to the consumer's mobile device by e-mail in a pre-configured frequency (daily, weekly). This will allow the user to identify the periods when water consumption is above average and thus control the use of water and even find possible leaks in the house. For greater control, just after the water flow sensor, a solenoid valve will be placed, also connected to the Arduino board, and this valve will allow the closing and opening of the water flow, which can be done remotely from a web application. Through previously registered parameters, the application will have autonomy to take some actions, and may even close the water flow automatically or through a remote request of the user (resident of the house). With this system, we’ll be able to control the water wasting and we’ll finally have a conscious use of this limited and important resource in people’s lives.
