Estudo técnico de rede de sensores sem fio para aplicação em sistema de hidrômetros digitais

Abstract

Water, despite being a renewable natural resource, is one of the scarcest resources in its drinking form, being available in only 0.5% of the total on the planet. Although Brazil does not suffer from water crises, the country stands out negatively for waste, either through fraud with direct clandestine connections or ways to block water meters. This factor has a financial impact on water distribution companies and even consumers. With the advancement of electronics, solutions have been developed to try to avoid both waste and fraud. In addition, another relevant factor to be highlighted is the rates of work accidents with the employees of these water distribution companies in their daily activity for reading and cutting distribution. In these situations several times the employee comes across loose dogs, exalted residents who do not accept the distribution cut and etc., in these cases aggression and bite injuries of these animals occur very often. For this reason, this work will address a study for wireless sensor network applications for application in water distribution companies. In order to allow data capture, transmission and analysis without the reader’s intervention. In addition to the reasons mentioned above with the application of wireless sensor network, the company may obtain some cost reductions such as labor lawsuits, compensation to employees, fuel by moving teams to the workplace, among others. The objective and methodology adopted for the development of this work aims to study the technologies existing in the market and to verify which would be the best choice for the application in this system and a possible development of a pilot project.
