Abstract: Based on the heart rate monitor front end AD8232 chips and Zigbee system solutions CC2530 single chip, the wireless ECG monitor has been realized in order to implement the acquisition, processing and wireless transmission of electrocardiogram signal. Meanwhile, the real-time heart rate has been calculated and wirelessly transmitted. The wireless ECG monitor is characterized by low power consumption, small size and simple operation. It can be seen from the experimental results that the wireless ECG monitor designed in this paper can successfully obtain favorable ECG data and real-time heart rate data and display it.
