The implementation of Internet of Things (IoT) technology is transforming learning environments with the introduction of high-level automation, which raises efficiency and optimizes resources. This paper demonstrates the design and assessment of an end-to-end IoT-based Smart Classroom Automation System, prototyped and designed with the Arduino Uno microcontroller as its processing unit. The system employs a mesh of intelligent sensors, mostly PIR sensors, to provide real-time detection of occupancy, supporting dynamic resource management of classrooms. Relay modules are important interfaces, allowing automated switching of electrical devices like lighting, fans, and projectors on the basis of occupancy and programmed schedules. The primary goals of this system are to greatly increase energy efficiency through power saving from unnecessary power consumption by controlling appliances based on occupancy and to increase ease of operation for teachers and administrators by reducing manual intervention in the repetitive classroom management procedures. Smart motion sensor-based lighting and appliance control are among the fundamental features that maximize utilization of resources only when necessary, complemented by remote monitoring and management through seamless IoT integration. This enables authorized users to remotely control and access the system through a mobile app or web portal, with real-time classroom status information and remote adjustments. The successful installation and initial pilot of this prototype show the promise of smart classrooms to maximize resource utilization, deliver a more effective and responsive learning space, and provide a scalable and sustainable technology platform for contemporary educational establishments. By automating mundane procedures and facilitating remote control, the system encourages a more effective and resource-savvy way of managing classrooms, leading the way to future applications of sophisticated technologies in academic environments
