Led Strip with temperature

hi! turn on rgb led strip, depending on temperature normal temperature sensor... our sketch, verificated arduino, does't work concretely, because shows high temperatures (like 100°c). please us??


 thanks lot!!!!

code: [select]

#define red       9// pin red led
#define green    10 // pin green - never explicitly referenced
#define blue     11 // pin blue - never explicitly referenced
#define size    255
#define hue_max  6.0
#define hue_delta 0.01
#define soglia1  32
#define soglia2    25
#define impin    0

void setup ()
{
  serial.begin (115200);
  pinmode(red, output);
  pinmode(green, output);
  pinmode(blue, output);
  }
  float tempc()
  {
    float raw=analogread(impin);
    float percent=raw/1023.0;
    float volts=percent*5.0;
    return 100.0*(volts-0.5);
    }
   
    void loop ()
    {serial.print("temperatura=");
    serial.print(tempc());
    serial.print("\260c;");
    serial.println();
    if(tempc()>soglia1){
      digitalwrite(red,high);
      } else {
      digitalwrite(red,low);
      }
     
    if(tempc()<soglia1>soglia2){
      digitalwrite(green,high);
      } else {
      digitalwrite(green,low);
      }
   
 
    if(tempc()<soglia2){
      digitalwrite(blue,high);
      } else {
      digitalwrite(blue,low);
      }
      delay(500);
      }
   

firstly, define "normal temperature sensor." there many types.

how ascertaining temperature read?
