Other Parts Discussed in Thread: AFE4403EVM

Hi,

I m working with AFE4403EVM with the sensors provided by the kit. I am measuring the heart rate in which i able to see the analog waveform. Thing is i just want to know the exact heart rate value in digital. Whether it is possible to find the digital output. If not, is there any other alternatives.

Regards,

Hello Gokul,

Unfortunately we are not Medical Equipment manufacturers to comment on the accuracy of the calculation for medical grade HRM devices. There may exist patented HRM algorithms for the medical devices.

There are numerous resources that can help you to develop your own algorithm. Refer to John Webster's Design of Pulse Oximeters. This book is an excellent resource to help you get started.
