hey Mack,

But if VDD is a 3 volt lithium coin cell whose voltage decreases over time, will that make the temperature also become less accurate over time?

Although, even if that is the case, that may be an acceptable amount of drift for this type of project.

Thanks I'll have to break out the breadboard (DANG!... Now the fun starts)

Still open to suggestions, though.
Price is really the main factor for my needs.
