IoT Learning Box

The IoT Learning Box is the ideal solution for university students, providing state-of-the-art, hands-on incorporation of IoT technology in an educational setting. It supports a lot of features which enables researchers and students to explore different aspects and develop different applications in IoT field. The most popular protocols used for the realization of IoT are MQTT, COAP, and HTTP. Sensors used with IoT Learning Box are the building blocks of the system which can collect values of different parameters. On-Board Micro-Controller ESP32 transmits information to Thingsboard open-source IoT Platform. Thingsboard will make the values of collected parameters available over the internet so that they are globally accessible.

Benefits to User

The kit is primarily for following users:

    • Students learning about Engineering at a technological University e.g., introductory first-year engineering courses and disciplines like Mechatronics, Electronics, Computer, Instrumentation, Control & Automation can learn about the Internet of Things (IoT) and implement that learning in further research and project development.
    • Professors teaching graduate and postgraduate engineering courses who want practical resources to explain and demonstrate Internet of Things (IoT) concepts in both lab and classroom environment can utilize IoT Learning Box and make the students understand well.
    • Makers with an interest or background in engineering, either professionally or as a hobbyist can interface multiple sensors to collect data and perform efficient processes using IoT Learning Box thus saving time and money.
