【Abstract】 The 89C51 Microcontroller is used to develop the hand-held DD detector to detect the concentration of alcohol in gases. This paper reports the technologies of anti-interference, system compensation and system self-checking adopted in software design which not only simplify the circuit but also improve the sensibility and reliability of the instrument.更多还原
