I am hoping @theatrus and others can chime in, I know he has built some and I finally got fed up and bought some real DS18B20 to build myself. I think the ones on Sparkfun - https://www.sparkfun.com/products/11050 are quality units but they are always on backorder so I decided to make some myself. My main question is do you pot the whole chip in epoxy or just use it to seal up the enclosure. I have been having issues with some probes, even when sealed with silicone still have had some that water is getting into them. I am just going to print some pteg cylinders and put the chips in that but wanted to know if you pot the whole chip or just seal the top.
Thanks
