PURPOSE: A sensor node for a magnetic communication is provided to perform communication between a sensor and a reader through a magnetic field, thereby collecting the sensing information of a sensor even in area including water, soil, or metal. CONSTITUTION: A magnetic field communication unit(130) transceives data through a magnetic field. After a sensed signal of a sensor unit(110) is converted into a digital signal, a control unit(120) converts a digital signal by a sensor processing algorithm into sensing information. Only if a request of a reader(20) is received through a magnetic communication unit, the control unit controls the transmission of the sensing information through the magnetic communication.
