The inspection instrument of temperature and humidity for Fluo-curing Barn was designed based on ARM and WinCE operation Platform with the small embedded database called SQLite3.The system struc-ture for the inspection instrument, the characteristic and the detailed process of porting in WinCE platform of SQLite3were introduced.The specific application of SQLite3database in the inspection instrument was ana-lyzed in detail.Experimental results show that the application of SQLite3achieved a good result, the tempera-ture and humidity data can be savable and manageable, and the technical curve of temperature and humidity dur-ing the process of drying tobacco was obtained which prepare the conditions for follow-up steps.
