This article is devoted to the modeling of the software and hardware complex (SHC) “Polygraph” on the basis of freely distributed microcontroller platforms. In the work, the analysis of primary sources was carried out and the most promising microcontroller platform for the purposes of visual modeling and training to work on such devices was chosen. Within the framework of modeling tasks, on the basis of a number of criteria, the most optimal automated system for the design of devices has been determined. Using the chosen toolkit, the authors modeled the first educational test version of “Polygraph” with the ability to display some parameters measured by real SHC. The article considered the connection of the following sensors of the SHC “Polygraph”: pulse, body temperature and respiratory rate. Based on the work done, it was concluded that this development is promising and relevant for design purposes and training in work on devices such as “Polygraph”.
