Water is one of the most valuable assets for humanity, it represents life, but its misuse, misapplication and inappropriate distribution can result in considerable losses, escalating to major problems. The objective of this study is to present a solution based on the Internet of Things, for domestic monitoring and control of water distribution, to prevent waste. We adopted an IoT-Ontology approach to ensure semantic (solid representations) between entities and other devices. The results presented in this study have been achieved by initially considering a low cost and low power consumption device. Further implementations of the solution presented will consider improvements of the experimental testing for end users and device development with government funding agencies.
