This research presents the design and implementation of a low-cost, modular Industrial Internet of Things training kit aimed at enhancing hands-on IIoT education in academic and experimental settings. The primary goal was to bridge the gap between theoretical learning and practical industrial automation through the development of a WiFi-enabled educational trainer based on the ESP8266 microcontroller. The system integrated DC and AC loads to simulate real-world electromechanical components commonly found in flexible manufacturing systems and computer integrated manufacturing. A web-based graphical user interface was developed using HTML, CSS and C++ within the Arduino IDE, facilitates wireless control. Seven different basic and fundamental experiments were conducted focusing on hardware architecture, device interfacing, wireless communication, and internet network connectivity. Results demonstrated effective control of resistor connected LED, DC, and three-phase AC loads, with a control response time of less than 250±2 ms and a wireless range up to approximately 30±2 meters. The uniqueness of the work is its scalable design that is accessible and IIoT literate, particularly in the developing countries, such as Pakistan. Although the limitations are limited to basic analytics and absence of encryption, the limitations are to be improved eventually. The kit provides a viable basis of IIoT skill building and helps in smart manufacturing projects that are in line with Industry 4.0.
