noise signal overpowers heartbeat signal

[ghanding]

Hello!

When I read the signal from my pulse sensor, the waves always appear at the same frequency. Therefore, the bpm always shows up the same: for different people, before and after exercise, and with and without a finger often times.

I think the sensor is registering a noise signal that is larger than the actual heartbeat signal. For some reason, the noise signal appears like a regular looking waveform that completely overpowers the heartbeat. I don't know what could be causing this other than a defective sensor. I ordered the real product, not a knockoff.

Thanks!

@ghanding Please provide a couple of things for us to troubleshoot.
Can you send a screen shot of the signal that you're seeing?
What Arduino board are you using? What OS?
Also, please send a pic of the Pulse Sensor you are using.
