I recently got an SEN0395 board to try out but am having trouble understanding how it works.

I followed this tutorial here:

https://wiki.dfrobot.com/mmWave_Radar_Human_Presence_Detection_SKU_SEN0395#target_6

And my Serial Monitor output is just constantly outputting ‘1’. From what i know is that this means it is successfully detecting the presence of a moving body, where an output of 0 on the other hand means there's is nothing detected.

What I am trying to figure out is how to configure/understand the parameters to increase/decrease the detection area. Am also trying to find out how to test its accuracy.

For e.g. ^

void DetRangeCfg(float parA_s, float parA_e, float parB_s, float parB_e, float parC_s, float parC_e, float parD_s, float parD_e);

^ what i got from the tutorial is that by adjusting the above code you can adjust the parameters of the SEN0395 sensor, but have tried and always get an error where i am unable to compile my code.

Does anybody know why or what else i could try to solve this?
