Issue with sensor voltage

[HarrisL2]

Using the PulseSensor_BPM example, I was able to get the BPM effortlessly at first, however, after a few days I did the same thing again, but this time the values outputted by the program were nonsensical.

Here is the data from when the sensor stopped working properly. When it was working it looked exactly like those provided in the tutorials.

In order to help you, I need to know what Arduino hardware you are using and also send a picture of your Pulse Sensor so that I can verify it is legit hardware.
