Vital capacity instrument owing to the ATmega8

This paper summarizes the function and characteristic of ATmega8 and MPX2010DP,describes every parts of circuital design about the vital capacity tester,and gives the key sub program design which realizes system function.The system not only guarantees measures high-accuracy and high sensibility,but also uses ATmega8,the core of control,that it facilitates wiring design.The calibrate realization method of the instrument has been studied and proposed,it also realize its credibility.
