The topic that takes software engineering theory as a guide is by means of monitoring system to reflect and realize the basic functions of PC software so as to achie e the purpose of studying the subj ect. The sensor that possesses not only low-cost characteristic but also rapid, flexible deployment capabilities has become an important part of our e eryday life and greatly changed our li es. In this paper, the main design is PC control of data acquisition system. The single chip data is gathered and set by the way of calling serial communication procedures to control the serial communication between PC and MCU. The system possesses friendly interface, simple operation. It also can be learned and used easily. It is stri ing to achie e the required obj ecti es and requirements of the software at the aspect of the o erall program.
