通过DS18B20读取温度（范围-55C~125C，精确到小数点后一位），通过4位数码管显示出来。 当温度为正且百位为零时，不显示，当温度为负时百位显负号。当温度百位和十位都为0时0都不显示。-Read through the DS18B20 temperature (range-55C ~ 125C, accurate to one decimal), through four digital tube display. When the temperature is zero and 100, do not show, when the temperature is significantly negative at minus 100. When the temperature is 100 and 10 are not displayed 0:00.
