Thanks mackrackit:
I do not have any problem to talk with the SHT_75.
I am able to get signed temperature tto.
My problem is to compute RHtc with picbasic pro and to compute DEW POINT with its sign.
Thanks for help

Here is a little about both for working with an EEPROM, maybe it will get you started?
