PURPOSE: A magnetic field communication method for transmitting sensing information is provided to install a wireless communication interface between a reader and a server, thereby increasing transmission distance. CONSTITUTION: A sensor node configures sensing information by a sensing signal of a sensor unit(S410). The sensor node transmits the configures sensing information to a reader through a magnetic field communication unit(S430). The reader transmits the sending information to an AP(Access Point) through a local wireless communication(S440). Based on TCP/IP, the AP transmits a local communication packet to a server(S450). The server configures sensing DB by the sensing information(S460).
