High Resolution Temperature


I'm new to hardware development and I'm looking to read human body temperature (oral) with the arduino. All of the thermocouples I've found have resolution of .5 degrees C, and I'm looking for one with .1 or lower (like a basal thermometer). Does anyone know of any that do this, or is there another type of sensor that I'm not aware of?

Thanks in advance,


maybe the DS18B20? from the datasheet:"The core functionality of the DS18B20 is its direct-to-digital temperature sensor. The resolution of thetemperature sensor is user-configurable to 9, 10, 11, or 12 bits, corresponding to increments of 0.5°C, 0.25°C, 0.125°C, and 0.0625°C, respectively. The default resolution at power-up is 12-bit"


This is exactly what I was looking for! Thanks very much.
