I need a temperature sensor recommendation with the following key specification:
I2C Interface with at least four addresses
-10 to 85°C range (min)
Isolated from ground sensing.
The last requirement is important and I originally picked the TMP275. It meets all of my requirements but it says to mount it on a PCB and use the copper pad connect to the end pin of the TMP275 as the main contact for sensing temperature. The problem is that I want to sense temperature on a metal object that I don't want to connect to GND. Does anyone have a better part suggestion for this application? Thanks.
