Abstract A real time intelligent detector based on AT89C52 single chip computer is developed. The instrument implemented the functions of detection and control for air pressure，temperature and humidity in sealed cabin，and offered parameter settings，LCD real time data display，audio and visual alarm，and printout of detecting results，as well as serial communication，etc. The detecting is automatic，the measuring results are in digital，and the functions are diversified. The measuring and control accuracy in performance detection of sealed cabin is enhanced and the labor intensity of operators is reduced.
