PURPOSE: A buried type alarming device with respect to intruders is provided to reduce cost and time required for operating the device and maximize the intruder detecting effect of the device. CONSTITUTION: An impact pressure sensor(2) detects an intruder. A battery(1) supplies power to a sensor controller(3). The sensor controller transmits intrinsic data from a sensor wireless transferring part(4) to a central controlling part(30) through an antenna. The central controlling part receives the intrinsic data. A microcomputer controlling part(13) reads the intrinsic data. A displaying part(15) displays installed position information.
