Abstract
Rapid development of automation technology makes people life very simple and easy. In today’s world, all of them depend only on automatic systems over manual system. An IoT-based smart classroom system mainly deals with the automation of electronic appliances in a classroom based on the Internet of Things (IoT) protocol called MQTT. The system architecture is comprised of several wireless nodes, a middleware, and user interface. All the wireless nodes communicate over dedicated or existing network with the middleware. This communication is based on Message Queue Telemetry Transport (MQTT) connectivity protocol which is designed for Internet of things. The MQTT protocol uses publish/subscribe-based messaging on the top of TCP/IP protocol. Through the user interface section, a user can interact with middleware of the system. The interaction is done by recognizing the command of the user through his speech. Mainly, secret commands are used for the interaction with the middleware. Raspberry Pi is the backbone of the system. It operates as a middleware, in the system architecture. Wireless nodes used in this system are called as Node MCU, and this Node MCU is placed in each classroom. After the execution of user interface section, the control is forwarded to the middleware which is placed in the staffroom. Finally, based on the user secret commands, the automation of appliances of each classroom will be done through Node MCU resulting in classroom automation.
