Briancui

#include <OneWire.h>
#include <DallasTemperature.h>
#include <LiquidCrystal.h>
LiquidCrystal lcd(12, 11, 5, 4, 3, 2);
#define ONE_WIRE_BUS 9
OneWire oneWire(ONE_WIRE_BUS);
DallasTemperature sensors(&oneWire);

void setup(void)
{
  lcd.begin(16,2);
  Serial.println("Dallas Temperature IC Control Library Demo");
  sensors.begin();
}

void loop(void)
{
  lcd.setCursor(0,0);
  sensors.requestTemperatures();
  lcd.print("Temperature  is: ");
  lcd.setCursor(0,18);
lcd.println(sensors.getTempCByIndex(0));
lcd.print("C");

}

查查显示器资料,有的显示器会有内置特殊字符,包括摄氏度
