For those of you who want to make a simple temperature-sensing relay module (to control AC/DC and whatnot), you might want to take a look at this DIY that uses DS1621 and Atmega ATTiny2313 microcontroller.

It contains only a few parts, a DS1621 temperature sensor, a attiny2313 micrcontroller,three LED’s one relay and some resitors. I have made a little printed circuit board for it.
