PitDS18B20 - Sonda di temperatura DS18B20

L'utilizzo della sonda di temperatura DS18B20.

Fonte principale Constantin Dimitrov.

Cosa serve:

• DS18B20
• cavetti

Codice sorgente:

#include "OneWire.h"
#include "DallasTemperature.h"
 
// Data wire is plugged into pin 2 on the Arduino
#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();
}
 
 
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.print("DONE");

  Serial.print("... Temperature is: ");
  Serial.println(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
    delay(1000);
