If anybody is looking for a digital temperature meter using PIC Microchip and DS1820 temperature sensor, here's one that I recently completed. It displays temperature on LCD in both Celsius and Fahrenheit scales and also provides a toggle switch for LCD backlight. The hardware and firmware are available too.
