Title: ALARM SYSTEM USING MICROWAVE SENSORS
Abstract:
The present invention relates to an alarm system, using microwave sensors, comprising: a first microwave sensor attached on a space in which a person sleeps; a second microwave sensor provided away from the first microwave sensor; a reception unit for receiving a first signal and a second signal from the first microwave sensor and the second microwave sensor, respectively; and a distinguishing unit for determining that there is a person in the space in which a person sleeps if the strengths of the signals received from the reception unit are compared and the first signal is stronger than the second signal by a predetermined value or more. According to the present invention, the biological signal of a person can be sensed by means of the microwave sensors, the person's presence is determined and an alarm function can be operated.
