| Abstract: | In order to resolve the problem existing in traditional measuring process of temperature-humidity, the new 1-wire temperature-humidity combined measuring system is designed. In the system, the integrated humidity sensor HIH-3610 is used to measure relative humidity; the multifunction chip DS2438 is used to get working voltage and humidity compensating data; and humidity compensation calculation and display are implemented in the host computer through LabVIEW programming. Experimental results verify simple systematic hardware structure and high measuring precision of the measuring system. The design has a broad applicative prospect. |
