摘要
介绍了数字温度传感器DS18B20的特点和工作原理,基于DS18B20设计了一种温度数据采集系统,并给出了这个系统的硬件构成图和软件流程图。系统由一个单片机电路和8个DS18B20数字传感器构成,结构简单,功耗较低,测量范围为-10℃^+100℃。若所测温度超出设定范围,单片机上的器件就会自动报警。
This paper introduces the characteristics and working principle of a digital sensor DS18B20. A temperature data acquisition system is designed based on the sensor,and the hardware structure and software flow chart of this system are given. The system has simple structure and lower power consumption. The temperature measurement range of the system is -10℃ ~ 100℃. If the temperature goes beyond the set one ,the system will give an auto alarm.
