The present invention relates to a communication technique, which is a convergence of IoT technology and 5G communication system for supporting higher data transmission rate beyond 4G system, and a system for same. The present invention can be applied to smart services (e.g. smart homes, smart buildings, smart cities, smart cars or connected cars, health care, digital education, retail businesses, security- and safety-related services and the like) on the basis of 5G communication technology and IoT-related technology. A sensor management terminal, provided in an embodiment of the present invention, comprises the steps of: generating a constituent image of a space in which a sensor is installed; obtaining a sensor identifier of the sensor on the basis of the constituent image; obtaining the sensor information of the sensor corresponding to the sensor identifier; determining a detection area of the sensor on the basis of the constituent image and sensor information; and displaying the determined detection area on the constituent image.
