Programming a Digital Temperature Sensor connected to Arduino UNO

Other Hardware Sensors

I am trying to program a DS18S20 Digital Sensor connected to Arduino UNO using Arduino 1.0 Software
I think that I have connected everything ok (attached photo).
This is my program:

#include <OneWire.h>
int DS18S20_Pin = 2;
OneWire ds(DS18S20_Pin);

void setup(void) {
Serial.begin(9600);
}

void loop(void) {
float temperature = getTemp();
Serial.println(temperature);
delay(100);
}

float getTemp(){
byte i;
byte present = 0;
byte data[12];
byte addr[8];

if ( !ds.search(addr)) {
ds.reset_search();
return -1000;
}
if ( OneWire::crc8( addr, 7) != addr[7]) {
Serial.println("CRC is not valid!\n");

}
if ( addr[0] != 0x10) {
Serial.print("Device is not a DS18S20 family device.\n");

}
ds.reset();
ds.select(addr);
ds.write(0x44,1); // start conversion, with parasite power on at the end

delay(1000); // maybe 750ms is enough, maybe not
// we might do a ds.depower() here, but the reset will take care of it.

present = ds.reset();
ds.select(addr);
ds.write(0xBE); // Read Scratchpad

Serial.print("P=");
Serial.print(present,HEX);
Serial.print(" ");
for ( i = 0; i < 9; i++) { // we need 9 bytes
data = ds.read();
_ Serial.print(data*, HEX);_
_ Serial.print(" ");_
_ }_
_ Serial.print(" CRC=");_
_ Serial.print( OneWire::crc8( data, 8), HEX);_
_ Serial.println();_
_}*_

This is compiling and charging correctly in the Arduino Board, but I dont receive the result in the screen.
Can someone help me?

I've had no luck with parasite power on these things although I know others have got it working. For test purposes, try providing power.

What do you get on the Serial monitor?

Have you tried using the DallasTemperature library? Might be worth using it to get you going, even if you ultimately want to roll your own.

Finally, please put your code in code tags using the # button above.
