Coding

<source lang="c++">

1. include <OneWire.h>
2. include <DallasTemperature.h>

// Data wire is plugged into pin 2 on the Arduino

1. define ONE_WIRE_BUS 2

// Setup a oneWire instance to communicate with any OneWire devices // (not just Maxim/Dallas temperature ICs) OneWire oneWire(ONE_WIRE_BUS);

// Pass our oneWire reference to Dallas Temperature. DallasTemperature sensors(&oneWire);

void setup(void) {

 // start serial port

Serial.begin(9600); Serial.println("Dallas Temperature IC Control Library Demo");

 // Start up the library

sensors.begin(); pinMode(11,OUTPUT); }

void loop(void) {

 // call sensors.requestTemperatures() to issue a global temperature
 // request to all devices on the bus

Serial.print(" Requesting temperatures..."); sensors.requestTemperatures(); // Send the command to get temperatures Serial.println("DONE");

Serial.print("Temperature for Device 1 is: "); Serial.print(sensors.getTempCByIndex(0)); // Why "byIndex"? // You can have more than one IC on the same bus. // 0 refers to the first IC on the wire

if (sensors.getTempCByIndex(0)>25.5 && sensors.getTempCByIndex(0)<27) { digitalWrite(11,HIGH); } else{ digitalWrite(11,LOW); }
