Summary:The utility model discloses an inductive remote alarm circuit comprising a power circuit, an induced circuit, and an alarm circuit. The inductive remote alarm circuit is characterized in that the power circuit comprises a power U1, a resistor R1, a capacitor C1, a capacitor C2, a diode T1, and a diode T2; the induced circuit comprises a chip IC1, a chip IC2, a diode T3, and a relay J; and the alarm circuit comprises a diode T4, a horn B, a capacitor C2, a capacitor C3, a chip IC3, and a chip IC4. The inductive remote alarm circuit uses a TX982 microwave induction controller. The TX982 microwave induction controller, by means of a microwave Doppler Effect, reflects echoes so long as a person or moving object enters an electric field within a range from 0 to 7 meters so as to trigger the alarm circuit. An acousto-optic and wireless signal emission alarm mode is used. A host can be timely informed of cases in home even if not at home. The inductive remote alarm circuit is simple in structure, stable in performance, sensitive in reaction, and low in false alarm rate.
