Design of Infrared Spectrometer Based on DSP

Abstract:

For the sake of evaluating the content of mineral oil and in water, and further more we can judge water quality pollution, we finally develop an infrared spectrometer based on STM32 which is on the basis of infrared spectrophotometry. The instrument realizes calculating the absorbance and concentration automatically with the help of high-precision pyroelectric infrared sensor and signal processing circuit. Besides it combines with built-in A/D converter and USB data transmission module, it can draw the standard curve on the host computer. Experiment results show that the instrument is accuracy enough and simple enough to use.
