digital temperature sensors

[URGENT]

i'm trying to design a circuitry which will trigger a response when the
temperature sensors register a particular temperature.

Problem: I'm not exactly sure what should be in the circuit. CAN ANYONE
HELP ME?

u can also send your suggestions to inalcanzable2000@yahoo.com.

MUCHAS GRACIAS

This gadget is called a thermostat. You can buy one at Home Depot. Da

How accurate? How repeatable? How rugged? What temperature? What time
constant? How many? (one benchtop rig or 100K units per month?)

temperature range: 30-50 degrees Celsius
I'm trying effect cooling so i want to start cooling when the temperature
goes above 27 degrees
and stop when it goes below although i doubt it will based on our climate.
