Apparatus and method for controlling lighting using wireless sensor network

An apparatus and a method for controlling lighting of a big office by using a wireless sensor network are provided to collectively turn off lighting lamps placed in a predetermined area if a person does not exist in the predetermined area, thereby preventing unnecessary energy consumption. A plurality of sensor nodes(100) senses whether a person exists in a predetermined area. The sensor nodes wirelessly transmit human sensing signals. Sync nodes(200) input the human sensing signals. The Sync nodes collectively control lamps(10) in the predetermined area based on the inputted signals. The human sensing signals comprises intrinsic ID codes which can perceive locations of the sensor nodes.
