Abstract

PURPOSE: A separation sensing apparatus having a sense circuit to sense a detaching state is provided to prevent loss of property and children by sensing the detaching states of a necklace and a bracelet and transmitting a state signal of a necklace and a bracelet. CONSTITUTION: A separation sensing apparatus having a sense circuit to sense a detaching state includes a loop part(20), a transmitter(30), and a receiver. The loop part(20) is formed with a conductive material. The transmitter(30) includes a circuit(34) for sensing state of a loop part and CPU(32). The circuit(34) includes a capacitor, a resistor, and an AC power source in order to sense a state of the loop part. An A/D pin is connected to a contact point between the capacitor and the resistor. The CPU(32) decides the state by detecting a variation the electric potential of the contact point according to a variation of inductance of the capacitor and the loop part. The receiver receives a state signal of the loop part.
