Abstract: A method of designing an indoor wireless sensor network using augmented reality The method comprises the steps of: acquiring environment data including at least one among a temperature, humidity, brightness, and an inclination using a sensor terminal in a wireless sensor network; storing the environment data in a table of a database; correcting a location of the sensor terminal using a terrestrial magnetism sensor and an acceleration sensor that are attached to the sensor terminal; matching the stored environment data to the corrected location of the sensor terminal and augmented reality; and displaying the environment data matched to the augmented reality. According to the present invention, data collected through sensor nodes is delivered to a user using a sensor network and augmented reality. Thus, the data delivery can be more convenient compared with a conventional technology that should always use a PC and requires an exact location of a sensor. Moreover, the use can acquire more correct and intuitive data since the data about the real environment is provided in real time through convergence of the reality and virtual reality.
