I am designing a simple PIC electronic POV (persistance of vision) project for the Boy Scout "Electronics" merit badge.

I would also like to include the ability to measure and display temperature. The "display" part is no problem as it will use a POV matrix.

It is the "Sensor" part I need help with. I am considering the DS1820 One Wire sensor, but would love to hear from this group's vast bank of experience. Low cost then simplicity is importaint.

Thanks in advance.
