How to deal with the limited magnitude of rcwl 0516 sensor?

we are getting a maximum value from the radar sensor around 4100. while walking or running or doing any movement we are getting a maximum value of 4100. My question is can we control its boundary in such a way that for walking, it will give different values and for running it will give different values. It must give different values for different activities. But due to its limited boundary, it gives a value of around 4100. I am attaching walking data. We can see the value of data can not cross 4100.
