Intellectualized High-Precision Environmental Parameter Monitor Based on Embedding System

摘要：

A kind of intellectualized high-precision environmental parameter monitor based on Embedding System is developed. The monitor adopts ARM microprocessor as core device, it has advantages of high precision and intellectualization, and has the function of thermometer, hygrometer and barometer which make the monitor precisely measure temperature, humidity and air pressure in laboratory and show these parameters on graphic dot-matrix LCD. The technical indicators of the monitor are: range of measurement parameters: temperature: -20℃-50℃; humidity: 0-100％ RH; air pressure: 500-1100hPa; precision in measurement: temperature: 0.3℃; humidity: 3％; air pressure: ±1.3 hPa. In this paper, the design of system software and hardware, especially the selection of sensor and porting of μC/OS-Ⅱ operating system, is introduced.
