Data sheet says its 1 kΩ at 0°C. It's got a table of resistor values, showing this is a PTC.
Create a voltage divider with a resistor that's roughly the value of this sensor at the average temperature you will use it, then you can read the mid point on an analog pin, calculate the resistance of the PTC, and using the table calculate the temperature (I'd just do a linear interpolation between values, will be good enough).
Basically the same as reading an NTC aka thermistor, just that in your case the resistance goes up with increasing temperature.
