摘要
通过运用DS18B20数字温度传感器的测温原理和特性,利用它独特的单线总线接口方式,与AT89C51单片机相结合实现多点测温.并给出了测温系统中对DS18B20操作的C51编程实例.实现了系统接口简单、精度高、抗干扰能力强、工作稳定等特点.
With using the measuring principle and characteristics of the numerical temperature sensor of DS18B20, making use of special characteristics of single line as the total line,and combine together with AT89C51 to realize several points temperature measuring. Also this paper give the example of the C51 program which is used to operate to the DS18B20. Make system have characteristics of simple, high accuracy, strong anti - interference ability ,stable work etc.
