Survey Of Smart Classroom

1. Introduction To Smart Auditorium Smart auditorium, as a place for listening developed from the classical open-air theaters. An auditorium auditorium includes includes any room intended intended for : — listening to music including theaters — churches — classrooms — meeting halls The design of various types of auditoriums has become a complex problem, because in addition to its various, sometimes conflicting, aesthetics, functional, technical, artistic and economical requirements, an auditorium often has to accommodate an unprecedentedly large audience. • In some ways, even the largest hall is no different from the smaller rooms, the basic acoustic criteria are the same smart auditorium solution provider in pakistan. — Must have a low ambient noise level from internal and external sources — Provide a reasonable level of acoustic gain — Provide appropriate reverberation time —Avoid artifacts such as echoes. • Hearing conditions in any auditorium are considerably affected by purely architectural considerations like: — Shape — Layout of boundary surfaces — Dimensions — Seating arrangements — Volume — Audience capacity Defects: 1. Echo 2. Delayed Reflection 3. Sound Shadow 4. Sound Concentration Advantages: They detect infrared light from a large distance, depending on how the PIR sensor is calibrated. PIR sensors are generally compact and can be fitted into virtually any electronic device. They are low cost and low power devices, have a wide lens range, , pretty rugged and can be easily interfaced with other devices o The same device can be used for two different purposes, thus providing multi- functionality features. Conclusion:

2. The main aim of the project is to save the power which is wasted in the Smart auditorium in Uae,Saudi Arabia due to the running of fan in case when auditorium is empty. The guiding system is simple system which is ultimately implemented to achieve power saving. Security is achieved by the metal detector at the entry door. The arduino controller is the backbone of our system, because everything from sensing the entry and exit, turning on the fan and its speed control depending on the temperature is managed by it. Constant power supply is required to maintain smooth functioning of the system
