I think thermal fuse with product no. STC208 will be of ur interest. It has a blow off temp rating of 98*c. cheers, ukapil

Can send you the code if you want. CharlieTheTuttle

Use Dallas DS1620 solid-state thermostat You don't need uC + sensor only DS1620 and power switch!!! This chip have on-chip E2PROM and you can program switch-on and switch-off temperature with 0.5C deg from -40 to 125C. This means that you have programmable temeperature hysteresis. You can drive power switch direct from DS1620 output pin. This works well and you can download source code examples from Dallas f*p site. You can make own programmer using PC paralel port or use Dallas DS1620 development kit. This is pure hardware solution and it is very secure. Regards
