The article considers a solution to the problem of mass collection of experimental data for modeling dynamic systems, which requires the creation of cost-effective and scalable technical solutions. The design of an automated microclimate monitoring system based on an ESP32 microcontroller is proposed, designed to measure key indoor parameters. The developed device is characterized by low cost and compactness, and its technical implementation includes power load control via galvanically isolated drivers and support for digital and analog sensors. Specialized software with a graphical interface has been created to control the device and collect data, which provides information structuring and storage for subsequent analysis.
