Here's one. It uses multiple sensors though. It uses the digital ds18b20 temp sensor.

And here is a TMP05 example:

You could also use a thermistor, and use the A/D converter for a simpler solution, but much less accurate.

but my PIC module is with the microcontroller, how do i build a circuit with the microcontroller?

I don't quite understand. Are you saying that your microcontroller came with a module, perhaps this one?

Or, are you saying that you want schematic drawn especially for your microcontroller?

The first link I gave had a pretty nice schematic for a pic16f876a.

A few more details would be helpful.

You will need to share more information if you want help. Do the boards have a manufacturer? How bout a part number? How bout a web link? Just "looks similar to", will probably not do here. Otherwise you code should "look similar to" the first, or second link I gave you.
