 Abstract
 In this paper, the theme is " The Design of Virtual Humidity Instrument By LabVIEW".It mainly describes in high temperature the humidity virtual meauring syetem design process and testing. This meauring system is used in the company's  USB-6009 NI data acquisition card. It is a programming design wich is based on the LabVIEW8.5 express platform. It is equipped with the following features : humidity corresponding detection,standard output,the establishment of humidity and time cure,humidity monitoring and alarm(adjustable minimum and maximum levels)and signal output,data storage. In this paper the functions of each module above and the entire test system for program debugging and research is analysed. The test system of environmental temperature and humidity did not ask for.
