摘要
文中介绍了DS18B20的功能特点,测温程序的软件实现流程及用逻辑分析仪分析其单总线实际工作时序;在温箱中利用DS18B20对火灾发生时温升作模拟响应实验,结果理想,可以作为复合型火灾报警器中温度检测部分,有利于对多传感器信号进行综合智能处理。
In this paper, the characteristics of DS18B20, temperature measuring program flow diagram and analyzed 1-wire bus working sequence using logic analyze are introduced. We made experiment to measure the rising of temperature when fire happened using DS18B20 in temperature box. The result is satisfied. So it can be used in smart fire detector and be propitous to the compositive processing to multi - sensors.
