Looking for a low cost, easy to use digital temperature sensor? This transistor like little guy is what you need.

The one wire Digital Temperature Sensor is great for measuring temperature in your projects. The DS18B20 is a very small thermometer which can be easily hooked into the Arduino through any digital input! It is a 1 wire digital sensor in 3 pin TO-92 package and can give 9-12 bit precision with digital to analog converter. It has a multidrop capability which simplifies distributed temperature sensing applications.

The DS18B20 can be powered by between 3.0V and 5.5V so you can simply connect its GND pin to 0V and the VDD pin to +5V from the Arduino. However, the DS18B20 can also extract its power from the data line which means we only effectively need two wires to connect it up. This makes it great for use as an external sensor. Each DS18B20 has a unique 64bit identification code which allows multiple DS18B20 to function on same 1-wire bus thus it is simple to use one microprocessor to control many DS18B20 distributed over a large area.

You can get started by using the Dallas Temperature Control Arduino library in your project.
