This paper describes the implementation of a system for remote management of technological processes using IoT technology. By utilizing the ESP8266 microcontroller, sensors, actuators, and other components, it enables monitoring and control of temperature parameters through a Web interface. The system allows operators to monitor the process in real-time and make adjustments as needed without requiring physical presence. Devices communicate via Wi-Fi signals, and the Web interface provides a simple graphical display of data and controls, increasing the efficiency and safety of the process. After planning and gathering the necessary components, testing of the microcontroller began. Using a simpler program, the libraries for the DS18b20 temperature sensor were first tested to ensure they correctly converted analog values into recognizable degrees Celsius. Next, the ESP8266 microcontroller was connected to the Web server using the appropriate libraries and configuring the baud rate. Once the connection was established successfully, HTML was implemented to display the Web page. The HTML setup was also tested to ensure proper implementation. The control logic was then programmed and integrated with HTML, with verification carried out using LED lights, which would later serve as signals. The control logic operates as follows, based on selections made from the web interface: • Cooling/Heating: The fan or heater is activated. • Standby: All systems are turned off. • Auto: The set temperature is maintained with hysteresis (+/- 1°C). After confirming that everything functioned correctly at the logical and software levels, the casing was built and actuators were connected through electromagnetic relays. During the final assembly, the nominal currents and voltages of the microcontroller pins and various process components were tested. With all connections and tests completed, the entire assembly was placed in the casing, connected to a power source separate from the computer, and the process was operated via the Web interface.
