AFE4404EVM: Heart Beat Analysis.

Part Number: AFE4404EVM

Hi,

We are currently using SFH7050 sensor. Can you please help us to  calculate and analyze heartbeat using from the below Waveform.

Thanks in advance,

Regards,

Neethu.

  • Neethu,

    From my observation, the heartbeat seems to be buried in noise. Can you get a better PPG signal? Is this taken from the wrist? Basically to calculate heartrate you take the number of peaks divided by the time.

    Our applications engineer will get back to you soon.
  • Hi Amy,

    Thanks for the reply.

    We have connected the module to  our Desktop system and placed the sensor module on the wrist. The sensor module was tightly mound using a Velcro and the  board was covered with a black cloth, to avoid interference from the LEDs in the control  board. The entire set was placed in a dark room, where there in no ambient light interference.

    Is there any thing else to be taken care of while capturing data.

    Kindly help us,

    Thankfully,

    Neethu

  • Hi Neethu,

    I would suggest first to get clean signal from finger tip.
    Also for better understanding please share some details such as sampling frequency, TIA gain, LED current.
