This system is a simple automobile exhaust detector,AT89S52 chip system control chip,
8155 for the expansion of the chip, ADC0809, as the signal conversion chip and other
chip-based,Supplemented by the corresponding program to completethe design of the exhaust
gas detector.This article discusses the basic principle of detection systems, hardwareselection,
software design.The hardware part of the circuit including the main control circuit, chip
expansion circuit, A/D converter circuit, display circuit.Software design in assembly
programming, modular design. Separately for each software module design, programming,
and debugging of the software, thus completing the complete software system.The system is
simple, easy toimplement,hasateaching value.
