Input raw PPG data clarification in example 3

[siddarth-murugesan]

Hi, I am playing around with MAX30105 Fingertip PPG sensor + Arduino for heart rate monitoring and I am trying to use HeartPy on the data collected from the sensor to analyze the heart rate. I looked into example 3 ('3_smartwatch_data'). It is mentioned as input raw PPG data is used. Could you please elaborate on that? I am confused because I have three possibilities for recording raw data in the sensor with RED alone or RED+IR or RED+IR+GREEN led modes. I am not sure what type of raw ppg data is expected for example 3 here from the sensor I possess. The range of values in the example 3 data files doesn't match the range of recorded data from the sensor as well. Thanks in advance
