In order to solve the problem of long-term monitoring on human physiological parameters in the absence of city electricity

adopt new light reflector NJL5501 R and analog front-end chip for ECG monitoring AD8232 at present

design a measurement system of human physiological parameters based on STM32L152

using low power consumption technology

such as dynamic power management

dynamic clock frequency control. The experimental results show that the system can complete the measurement of human blood oxygen

ECG and temperature parameters

features with low power consumption

small volume

it can monitor the physiological parameters longterm.
