It is observed that these types of devices take measurements, but they cannot transfer the measured data to the educational environment. appropriate, easily understood by students, and behaviorally guiding in a gradual manner It does not convert into a visual warning system. Additionally, current solutions automatically adjust the sound level according to predetermined threshold values. classifying and generating visual feedback through color changes based on this classification. There is no integrated control structure. 10 Existing systems are generally technical measuring devices and are specific to the classroom environment. designed, compact and user-friendly, with a wall-mountable or portable structure. It does not have an educational support system feature. Therefore, classroom noise cannot be automatically controlled. monitoring, evaluation according to threshold values, and real-time visual impact on students. An integrated system that enables the gradual generation of notifications in a way that raises awareness. An electronic control system is needed. Purpose of the Invention: The invention describes a classroom sound level measurement system that provides gradual visual warnings about silence. The purpose of the sensor system is to monitor the environment in educational settings, especially in primary school classrooms. 3 Continuously monitoring the noise and converting the measured sound data according to predetermined threshold values. Automatically classifies and provides gradual visual warnings based on this classification. by producing it, classroom noise levels can be controlled without the need for teacher intervention. The aim is to enable students to easily perform technical measurement functions. by transforming the classroom layout into a perceptible visual feedback mechanism, it becomes sustainable. 5 to contribute to its preservation in this way. Benefits of the Invention: ▪ The invention concerns a system that provides gradual visual warnings of silence based on classroom sound level measurement.
