SMT-160-30 Temperature Sensor

Hi all! I´m trying to read data from a Smartec SMT-160-30-50 with the code is shown in:

http://playground.arduino.cc/Code/SMT16030

but my Arduino Uno only read values such as 144,60 (in theory they are ºC, if they were Farenheit my room would be burning too :confused: ).

I´ve tried another code from the topic Temperature Sensor:

http://forum.arduino.cc/index.php?topic=41846.0

and in this case I only receive 0.

I´ve search in the Web and I haven´t found anything else interesting or different.

I´ve tried to read the sensor with pulseIn(my_pin, HIGH) function and I also get a 0.

Is there anything I am doing wrong? The connections are very simple (according to the playground tutorial). Is any timeout needed?(I´ve tried several values but nothing change).

Thanks in advance.

try this modified version that uses more samples in the same time

unsigned long now;
unsigned long lastOutput;

unsigned long sampleCount;
unsigned long highCount;

int sensorPin = 2;

void setup()
{
  Serial.begin(9600); 
  Serial.println("Start SMT16030");

  pinMode(sensorPin, INPUT);
  digitalWrite(sensorPin, LOW);

  sampleCount = 0;
  highCount = 0;
  lastOutput = 0;
}


void loop() 
{
  now = millis();
  if (now - lastOutput > 500)
 {
    float temperature = ((1.0 * highCount)/sampleCount) - 0.32)/0.0047;
    Serial.print(highCount);
    Serial.print(" / "); 
    Serial.print(sampleSize);
    Serial.print(" temp: "); 
    Serial.println(temperature);
    lastOutput = now;
    sampleSize = 0;
    highCount = 0;
    sampleCount = 0;
  }

  sampleCount++;
  if (digitalRead(sensorPin)) highCount++;

}

you can use this library :
