Abstract:
In order to adapt to the heart rate detection under the state of motion, using the low power con-sumption microcontroller STC11L01E as the control core, and using the performance excellent green photoelectric reflection sensor SON1303 to collect the heart rate signal, and through filtering, amplification, signal conditioning. Then send microcontroller to process, the heart rate data displayed on LED numeric tube after smooth anti-jamming algorithm and issue alarm signals when the heart rate is abnormal, the accuracy of heart rate was more than 98.5% under physical detection, so it’s effective. The whole system is designed with low power consumption.
