Same result...

posting in other forums they suggest me to do an i2cdetect and I get this result (picture)

This mean that Rpi doesn't recognize ADC 1115?

Perhaps should I weld again all pins..

Could you post a picture of how you are connecting the ADS1115 to your Pi?

I have no clear what is these readings. I get 26200 when dry and 9500 when complete submerged.
Is it 2,62V? mA? some connection can be wrong?

Thanks

That's 2.62V and 0.95V which sounds about right on the assumption the moisture sensor is being powered with 3.3V.
