Recently, as the increasing requirement on the stability, reliability and accuracy of environmental temperature and humidity data in the Tobacco Industry, a set of correcting ways of temperature humidity sensors has been fulfilled and a Data Acquisition System based on the MODBUS protocol has been designed and performed with the equipment of a temperature and humidity environment experimental case. The system includes data acquisition module,data processing module and data display and memory module, which using the SQL Server as the background data server. Moreover, the system communication applies the MODBUS RTU mode, resulting in the successful realization of temperature and humidity data acquisition, display, storage and inquires functions.
