A microcontroller-based wireless sensor network prototype was retrofitted inside a residential unit for its energy management. The wireless sensor network consists of wireless sensor nodes and a coordinator. Each sensor node consists of sensors and switches. The sensors measures the presence of the people inside the room and the ambient room temperature while the switches regulate lighting and control electrical sockets. The coordinator collects the data coming from the wireless sensor nodes, displays the status of the system in a graphical user interface (GUI) and stores the data in a database management system. Communication takes place in the network through XBee wireless radios that are configured to implement the ZigBee protocol. Based on the results, the proponents acquire a system reliability of about 93.33%. In addition to that, a power consumption reduction of about 10% was achieved.
