In this thesis, changes to be done into the photoelectric relays used on street lighting systems are proposed. It is intended to improve those systems, bringing social and economical benefits. Most of street lighting systems is comprised by high pressure sodium lamps, electromagnetic ballasts and photoelectric relays, which must turn on/off lamps on due time. Although simple, such a method has many drawbacks, as lack of fault diagnosis, energy measurement, time monitoring and remote control. By employing wireless communication and embedded computing, an innovative solution is presented. When such changes are applied into the photoelectric relay, a new device comes out - a wireless sensor/actuador node for street lighting management. Development steps of the device are reported. Testing procedures are undertaken to validate it and justify its use on the street lighting systems.
