Abstract
A visible spectrophotometer based on embedded linux and ARM is designed.The system uses the ARM processor as its control core
adopts average method and proportion formula to handle the testing data.It can digitally display transmittance and absorbance
automatically calculate solution concentration and draw spectrogram.The result of experiment shows that the system not only has the advantage of easy operating and complete functions
but also can inspect transmittance and concentration accurately.
