Aha okey im sorry for that soo. I want to use ADC1115 and soil moisture sensor. I get the correct values of measuring.i mean when my sensor is in the water a get 3230 and when is not it is an 14216. So is there any chance to convert this data in percenteges values of range 0% to 100%. I use the code from adafruit (Adafruit_ADS1015.h). I really hope u will understand.
