Abstract: A floor-mounted security device able to test personnel for metal material carried in or at the bottom of their footwear includes an induction module, a pressure sensing module, and an automatic alarm module. The pressure sensing module senses weight and pressure of a person standing, and outputs a trigger signal to the induction module to trigger operation of the induction module. The induction module can detect the presence of a metal mass by the change in a magnetic field, and output a control signal accordingly. The automatic alarm module outputs an alarm when prompted by the control signal.
