Thanks for the quick answers.
I changed all the cables that I use as indicated by QuickFix. So far everything works correctly but I want to monitor the sensor for some more time.
And Eriksl thanks for warning, i will review all my modules.

Yeah, if I2C communication is fine and the code doesn't have bugs (I assume you are using some kind of library or arduino etc.) then it must be the sensor that's faulty.
