Design of instrument of chestnut Based on Microprocessor

In this paper, the focus of this work was to design and manufacture the near infrared spectrum analyzer for chestnut com-ponents with filters. Using diffused reflection spectrum technology with the fixed wavelengths developed software and hardware of the INR spectrum analyzer to analyze chestnut components. The dominant parts contain: a lamp, a filters and a detector, microcontroller, keyboard, LCD. Friendly user interface for the computer is realized by VC++6.0 and such function as datum analysis, datum pro-cessing, datum cure displaying is realized.
