These factors depreciate the efficiency of the services provided, as well as, the use of energetic resources, because there is energetic waste and, consequently, financial resources that could be applied at the own public system illumination. The purpose of the work is create a prototype in substitution to the currently photoelectric relays used at public illumination, that have the same function, as well others: turn on or off the light bulbs remotely (control flexibility by the use of specifics algorithms supervisory), checking the light bulbs status (on or off) and wireless communication with the system through the ZigBee? protocol. The development steps of this product and the tests carried out are related as a way to validate and justify its use at the public illumination / O sistema de ilumina??o p?blica da cidade do Natal/RN apresenta problemas recorrentes no aspecto do monitoramento, visto que atualmente n?o ? poss?vel detectar em tempo real as l?mpadas que est?o acesas durante o dia, ou as que est?o apagadas (queimadas) durante a noite. Estes fatores depreciam a efici?ncia dos servi?os prestados, bem como, do uso dos recursos energ?ticos, posto que h? desperd?cio de energia e, consequentemente, de recursos financeiros que poderiam ser aplicados no pr?prio sistema de ilumina??o p?blica. Este trabalho teve como objetivo a cria??o de um prot?tipo em substitui??o aos atuais rel?s fotoel?tricos utilizados na ilumina??o publica, os quais possuem as mesmas fun??es, como tamb?m agregam outras: ligar ou desligar a l?mpada remotamente (flexibiliza??o do controle a partir do uso de algoritmos supervis?rios espec?ficos), verifica??o do status da l?mpada (acesa ou apagada) e comunica??o sem fio com o sistema atrav?s do protocolo ZigBee?. Relata-se aqui as etapas de desenvolvimento deste produto e os testes realizados como forma de validar e justificar seu emprego na ilumina??o p?blica
