PLC, Relay (DPDT), SMPS, Infra-Red through Beam Sensors, Temperature Sensor, Light Intensity Sensor.
Technology updating in day today’s life likewise in education system as well where automation up gradation has to be done hence our project is trying to put an effort to make a normal classroom into the an updated version of classroom .
“Controlling and Monitoring of Classroom using Programmable Logic Controller (PLC)” is an intelligent system mainly focuses on managing all the electrical system and monitoring the classroom using automation technology. It is the dual functioned project where both controlling the loads in which Fans and lights are turned ON/OFF and monitoring the classroom is done which counts the number of students presence and absence. It is employed to improve the energy saving of the classroom. The serves is done by providing a right amount of electric where and when it I s needed.
PLC is utilized extensively for automation of electromechanical process. It provides reliable communication of classroom automation with reduced cost. In this project, we propose the idea of designing a smart energy saving classroom to optimize the energy consumption. The PLC is easy to understand and the system provides multiple solution using single component. Although new but more efficient than previous systems, the PLC can become the epicentre to many new applications. Once the system is designed and implemented the only cause is that of maintenance. Each component serves a purpose in this system. Relays are used to control the output mode of operation. SMPS (Switch Mode Power Supply) works as a rectifier which used to convert AC current to DC current. So we can say that this new idea will be an innovative in the field of automation and smart technology in classroom.
