Design and implementation of portable multi parameter life monitor

With the improvement of people's living standards, more attention is given to health status. This is a higher demand for our modern medical facilities. How to let the sign detection equipment out of intensive care unit (ICU), out of hospital, become accessible and can be used for real-time monitoring of the life necessities is a major topic currently. Based on this, the CSN808 module is used to design human physiological parameters monitoring system, with single chip microcomputer, and the real-time monitoring of human physiological parameters is realized. The module is small in size, easy to be installed, and can be programmed by microcontroller to achieve the LED real-time display of heart rate, blood pressure, blood oxygen saturation and respiration rate measurements. The results show that the monitoring accuracy and operability of the system has achieved the expected requirements, and the actual values are basically the same. The module can work normally and right.
