It is incorporated with weighting,measuring body composition and analyzing HRV. The hardware is based on MPU. The circuits can magnify the weighting sensor signals,the-bioelectrical impedance signals,ECG signals and detect the QRS.

• 硬件设计以单片机为平台，设计了压力传感信号、生物阻抗信号、心电信号放大电路和QRS波的检出电路，同时还有液晶显示电路及单片机的接口电路。
