A gas leakage detector based on ARM hardware platform is designed

in order to improve the intelligence level of gas leakage detector.The system uses S3C2440 as its control core

adopts high precise A/D converter

two-channels gas path and the principle of pressure to detect the air tightness.It qualifies self testing

digital display

real-time plotting and data storage capabilities.The result shows that the system not only has the advantage of easy operating and meets the requirements of on-line real-time detection

bus also have good repeatability.
