The paper introduces an intelligent temperature and humidity Itinerant Detecting Instrument based on 32 bit microprocessor STM32 and data processing software of host computer. The acquisition instrument realizes the parallel measurement of temperature and humidity in 32 channels,and automatically identifies the type of sensor. The host computer data processing software can process the experimental data scientifically and generate records and certificates automatically. The paper describes the technical characteristics of the acquisition instrument from three aspects: hardware principle,program control logic and host computer data processing software. According to JJF 1101-2003 " Calibration Specification for the Equipment of the Environmental Testing for Temperature and Humidity",the acquisition instrument implements spatial distribution,data collection,data processing and record certificate generation to realize automatic detection of environmental test equipment.
