Need help with a pulse sensor, numbers look random

I bought 3 of these sensors and all 3 don't work correctly. At the moment I'm traveling, but when I return I intend to modify one of them and use it with a second amplification stage. Someting like this. [image]

All my 3 sensors don't work. I bought it on the Aliexpress website and I think I was scammed, or even the original product doesn't work well.
