$23 isn't cheap All gone now anyway. OT: You used the Dallas DS18S20 with a PIC? Having a few problems.
ChrisX: Sadly, I havent tried using the DS18S20. Ive been more into using thermistors and thermocouples. But, there are alot of people who like using the DS18S20 with pics, and I bet you can find something quick on goggle for example code.
