Development of the temperature and humidity instrument for clothing measurement based on virtual instrument

Temperature and relative humidity are two important parameters in research of thermal and moisture comfort properties of clothes,and making accurate and real-time measuring of them is a practical technology.This article introduces the temperature and humidity measuring instrument which is developed on NI virtual instrument technology and LabVIEW software.This instrument has many functions,such as multi-channel signals input,real-time data acquiring and processing,graphical display,file preservation,and overrun alarming.This instrument can be used in thermal-moisture comfort measurement of clothes and some other relative fields,which is flexible,versatile and obtains good results in experiments.
