This paper describes a home care system for elderly by four detached multi-sensor network. The sensor network detects several bio-signals in bed. It consists of the following four sensors. An ultrasonic sensor detects human motion. An optical fiber sensor detects respiration. A mat-type sensor detects heart rate and respiration, and heart rate accesses autonomous nerve system. A microphone detects cough with phlegm to suction. The ultrasonic sensor attaches to bed frame, the mat sensor set under the bottom of the mattress in bed, the optical fiber is in mattress, and the microphone set in bed side. The sensor network can detect essential bio-signals such as heart rate, respiration, cough with phlegm to suction and body movement with high accuracy.
