B.Tech CSE (IoT)

B.Tech CSE (Internet of Things & Embedded Systems) is a specialized undergraduate program that merges core computer science principles with hardware-centric engineering. It focuses on designing and developing intelligent, connected devices that form the backbone of the Internet of Things. The curriculum covers embedded systems (dedicated computer systems within larger devices), sensor networks (interconnected sensors collecting data), and edge AI (running artificial intelligence algorithms on local devices rather than in the cloud). This program is a response to the exploding demand for engineers who can bridge the gap between software and hardware in the era of smart everything—from smart homes and cities to industrial automation and healthcare.

Students gain hands-on experience with microcontrollers (like Arduino, Raspberry Pi, ESP32), real-time operating systems, communication protocols (MQTT, CoAP, Bluetooth, Zigbee), and cloud platforms (AWS IoT, Azure IoT). They also learn to implement machine learning models on resource-constrained devices, a skill known as TinyML. The program typically includes laboratory work, project-based learning, and internships with industry partners. Graduates are equipped for roles such as IoT Engineer, Embedded Software Engineer, Firmware Developer, and Edge AI Specialist. With the proliferation of connected devices—expected to reach 29 billion by 2030—this specialization offers a promising and future-proof career path.
