Temperature Control using a DS1621 Sensor and a ATtiny 2313 Micrcontroller
This Temperature Control project interfaces a DS1621 temperature sensor to a ATtiny 2313 micrcontroller, with some AVR Bascom code a relay is controlled based on temperature. This is a very useful project since it has many applications, you could use it to turn on your car block heater when it gets cold, or turn on your attic fan when it gets real hot in the attic.
