    I’m not familiar with the new C model, but I did use the older, now-discontinued one awhile back.  Without digging into the manual and the library too deep, I’m guessing it might be an I2C address issue?  The old model used 0xB8 whereas the new one uses 0x38.  So go into the ModularSensors/src/sensors folder and edit AOSongAM2315.cpp, find line 34 and change the address from 0xB8 to 0x38.
