    Abstract

    Aiming at the non-destructive, online and fast portable detection requirements of dried pericarpium citri reticulatae, a handheld non-imaging spectrum analyzer is designed based on the visible-near infrared spectroscopy technology using the AS7341 sensor. The analyzer uses STM32 microcontroller as the main control chip, which has various functions such as network connection, storage and display. The software and algorithm are designed for the microcontroller, which realizes the acquisition, processing, display, storage and transmission of spectral data. The experimental verification is carried out with different years of pericarpium citri reticulatae as the detection object, and the results showed that the accuracy rate of year identification of pericarpium citri reticulatae in the testign set is not less than 97%, which has practical application value.
