I don't recommend using LM335 sensor in your application.
Manufacturers say LM335 have 1 degree accuracy but i took two sensors from different series and temperature they show differs 2-3 C

It might be a bit more cost and functionality than you are looking for but try h**p://www.sensirion.com. They have temperature and humidity in one sensor (easy calculation of dewpoint) with an easy to use serial interface.[/url]

even more important than the sensitivity of the sensor is the way that sensor has been mounted. if sensors are mounted in a poor way it takes considerably long time before they reach equilibrium with the substance that you are trying to measure its temperature. if you mount two sensors exactly the same way and also calibrate them to compensate any possible error, there is no reason for such a difference .I have used LM35 happily many times. although it is analog, it is very precise and surely can give accuracy of 0.5 degree centigrade.
