Abstract: Data acquisition and processing system for air pressure monitoring based on MCS-52 single-chip computer is introduced in this paper. The single - chip computer technology is adopted in the system. AT89S52 is the control center of this system .The high-performance, lower-range pressure sensor  is installed on the stepper motor and detects the wind pressure when it rotates driven by the stepper motor. In addition, a wireless transceiver chip- PTR8000 is applied to this system. The wireless transmission of data from the testing circuit can be realized. The system can be controlled by users at the receiving end.  The system avoids the complicated on-site connection,  shows superiority in application flexibility, improves the working efficiency and reduces costs.

Keywords: single-chip computer;  pressure sensor;  wireless transmission
