A guest lecture on “IoT and Its Applications” was organized on 27th February 2025 at SACAS Auditorium. The session was conducted by Mr. B. Abdul Azhar, an AI/ML Engineer from TechKnots Academy LLP. The objective of the lecture was to introduce students to the fundamentals of the Internet of Things (IoT) and its real-world applications.

Mr. Azhar began the session by explaining IoT, its significance, and how it connects devices through the internet to automate processes and improve efficiency. He highlighted how IoT is transforming industries such as healthcare, agriculture, and smart cities.

He then discussed the difference between a controller and a processor, emphasizing that controllers are dedicated to executing specific tasks efficiently, while processors handle more complex computations required for multitasking.

The role of sensors in IoT was another key topic. He explained various types of sensors, such as temperature, motion, and humidity sensors, and how they help in data collection for IoT applications.

Moving forward, Mr. Azhar introduced students to types of microcontrollers, including popular ones like ATmega328 (used in Arduino) and ESP8266 (used in IoT applications). He also discussed the different types of Arduino boards used in IoT, such as Arduino Uno, Mega, and Nano, highlighting their functionalities.

The session concluded with an engaging discussion on building IoT projects using personal ideas and everyday problems. Mr. Azhar encouraged students to identify real-world challenges and develop innovative IoT-based solutions.

The lecture was highly informative, sparking curiosity and enthusiasm among students to explore IoT further. The event concluded with a vote of thanks, expressing gratitude to the speaker for sharing his valuable insights.
