Aiming at the advantages and disadvantages of the temperature and humidity data acquisition system was adapted at present, the design method was proposed for a new type of data acquisition system. It was used 51 single chip microcomputer as the core, and could provide four kinds of sensor interface such as thermocouple, thermal resistance, I2C and single bus. It could acquire 32 channel temperature and humidity data with good compatibility and expansibility. The device prototype was tested on the actual production workshop in Yunnan Tin Group,test results indicated that: By using the collector and the supporting software, this method could realize the communication of PC and single chip microcomputer. The monitoring parameters and results were displayed on PC real-time. The temperature measurement accuracy can reach ±0.5℃, and humidity measurement precision can reach ±3.0RH. The complete temperature and humidity curve obtained for liquor fermentation process. It can provide the reliable control curve for mechanized and standardized production.
