摘要
利用HiH-3610和DS2438获得相对湿度、工作电压和温度补偿数据,以DSP为数据采集处理器,综合利用单总线技术,设计了一种新型的温湿度度复合测量系统。该测量系统湿度测量范围0%~100%,分辨率±1%;温度测量范围-40℃^+125℃,分辨率±0.5℃。实验证明该测量系统的硬件结构简单,测量精度高,具有较高的智能化程度,容易实现多点和远距离测量。
Hill-3610 and DS2438 is used to get humidity, the data of supply voltage and compensating temperature, the technology of 1-wire is put to use synthesized ,which base on DSP. The new temperature-humidity measuring system is designed. Features of the system： relative humidity measurement accuracy ＋/-1%, Humidity measurement range from 0% to 100%. Temperature measurement accuracy ＋/-0.5℃, Temperature measurement range -40℃-＋125℃. The experiment tests that the measuring System has a lot of merit, such as simple structure, high accuracy in measurement, high intelligent, distant testing.
