There is a need that consumers track daily use and understand consumption standards to better organize themselves in order to obtain greater economy of resources. With the improvement of smart networks technology for better energy supply, a smart meter is not just a simple measurement gadget anymore, but it has additional functions, such as smart equipment control, bidirectional communication, which allows the integration among user and network, and other functionalities. Smart meters are the most fundamental components in smart power grids. Besides, the meters used with a management system can be used for monitoring and control home appliances and other gadgets, according to the users' need. A solution of an integrated and single system is efficient and more economical. Smart environments are becoming a key piece in the future green and sustainable energy grid due to power source integration and demand control capabilities. Advanced measurement systems make themselves necessary to the future smart grids operation. Smart measurement systems allows energy consumption monitoring of the end consumers, while provides useful information about the quality of energy. The information provided by this system are used by the system operator to enhance the energy supply, and different techniques - such as charge scheduling, management from the demand side and non-intrusive load monitoring - can be applied for this end. The Internet of Things (IoT) is becoming a great ally in the management of smart distribution and energy consumption in smart systems scenarios. This work aims to present and validate the development of an intelligent energy meter, following an IoT approach, and associated challenges and benefits. Given the IoT requirements, this dissertation explores a review analysis of the key features that smart energy meters should provide, along with the analysis of existing solutions that use smart energy meters for smart grids. A low-cost, multi-protocol, modular IoT-enabled smart energy meter design capable of collecting, xii processing and transmitting various electricity-related information, focusing mainly on the consumer side, is proposed, presented and validated. Finally, the integration of the solution with the middleware developed by IoT Research Group - Inatel, capable of receiving data collected by the smart energy meter, performing the necessary treatments and storing this data so that the application can, is presented via the Internet, access middleware data and make information available to users. The solution is evaluated, demonstrated, validated, and it is ready for use.", publisher = {Instituto Nacional de Telecomunica??es}, scholl = {Mestrado em Engenharia de Telecomunica??es}, note = {Instituto Nacional de Telecomunica??es} }
