Development of an Algorithm for Intelligent Analysis of Data From a Microprocessor-Based Portable Spectrophotometer

This article is devoted to the development of a microprocessor-based portable spectrophotometer for the analysis of substances in water, the development of an algorithm for analyzing data from the device, and the writing of software based on this algorithm. In addition, the article is devoted to assessing the applicability and relevance of this device for high-quality water monitoring. The article presents a structural diagram and an optical system diagram of a microprocessor-based portable spectrophotometer. In addition to the microcontroller, the portable device also uses at least two logical modules: a servo drive and a Bluetooth module. The principle of operation of the device's microcontroller is presented in the form of a structural diagram, the entire developed algorithm is divided into two main stages - a preparatory cycle and the main cycle in which samples are studied. A special algorithm has been developed that allows remote control of the spectrophotometer. In addition, the algorithm for intelligent data analysis has several operating modes and a calibration mode.
