Arduino and KTY81-210

You have a lot of possibilities to measure the temperature with an arduino. One simple solution is the usage of a KTY81 silicon temperature sensors.
Arduino describes on the playground the usage of KTY81-110. If you have an other type, you need to recalculate the temperature.

(Vcc 5+)--+-->2.7k--+-->kty81-210-->(GND)

          +->100nF--+-----> ADC2 (Analog Port 2)

Here is my code to use KTY81-210 with the arduino:
