Grove Heart rate finger clip Sampling Rate

Hi,
I am using Grove finger clip sensor to measure the heart rate using the sample code available online.Can anyone help me about the sampling frequency of this sensor. And how can i get the raw data so that i can check with different sampling rate .
Thanks in advance.

I checked the datasheet for you and I’m really sorry that I didn’t find the parameters you wanted.
