Public lighting is a fundamental asset for society, since its emergence, due to the important role it plays, bringing clarity in periods when natural light is absent, especially in urban areas, enabling the development of night activities, such as commerce, leisure, tourism and also helping to inhibit criminal practices during these periods. The public lighting system is a service that, of course, must accompany the growth of cities and the increase in demand, making system supervision and control even more important and necessary. Dependence on essential services like this, may mean that there is a need to obtain more and more new, intelligent and effective alternatives to maintain the services. This work aims to demonstrate how communication via XBee radios can be inserted in this context, and help in the supervision and control of public lighting. In order to achieve the objective, we sought to develop a project based on the formation of a communication network, using the ZigBee protocol, through the XBee radios, in which there is a supervision and control station and a remote station, simulating a public lighting spot, which uses an LDR light sensor to collect data from the environment, and sends it, through the ZigBee network, to the supervision and control station. The supervision and control station also has the Arduino platform, which uses the processing capacity to analyze the data received and send a control command to the remote station. The network formed by the XBee radios proved to be reliable, easy to initiate and good performance, thanks to the fast and stable connection of the modules, which allowed the remote node to send the collected data to the central and get the control remote back to the activation of the lighting point.
