Development of an intelligent prototype using turbine sensor for detection of leaks in buildings

Abstract

The recurrent water scarcity scenarios and limited availability raise the need for more efficient water monitoring and management. An intelligent device with renewable energy for monitoring water consumption and leak detection is an essential tool that can help reduce losses and waste in buildings. The methodological procedure was composed of identifying components for the development of the intelligent leak detection prototype, elaboration of the microcontroller programming, and subsequent installation for use. The research was carried out at the Federal University of Campina Grande (UFCG). The prototype was developed using Arduino's programming language, NodeMCU-type microcontroller with integrated Wi-Fi, turbine-type flow sensor with pulse counting, rechargeable battery, and solar energy supply via a photovoltaic panel, in addition to the necessary accessories for operation, with a total cost of BRL 159.98, a realizable value given the economic and environmental gains arising from the detection of consumption patterns at times when there are no activities in the place. The intelligent prototype worked satisfactorily, and automation detected up to 1.96% losses in the studied building, equivalent to 12.81 liters on October 30, 2021. In conclusion, it is possible to validate the use of the prototype for monitoring water consumption and leak detection in buildings, being an appropriate and low-cost tool to assist in water management in buildings.
