Abstract

The Library Room Noise Level Detector is very useful as a solution if the library room is not controlled so that it can be uncomfortable for other library visitors. This is what causes the importance of the availability of this tool as a solution for detecting library room levels. The purpose of this study is to design and make level detection in the library room that can provide a warning through a buzzer, Led dot matrix, and blynk as a display of decibel intensity and a notification if it occurs, with a case study in the library at the Ati Polytechnic Makassar. The research method used is the observation method by observing the object under study and then designing and manufacturing tools based on block diagrams and flowcharts made. After designing and making the tool, the tool will be tested and the analog sound sensor data used is taken. The results of testing in the library conducted at 09.00 - 16.00 showed that the highest intensity obtained was 64dB and the highest intensity obtained was 43dB. This system can be used to detect the levels in the room and activate alerts via buzz and Led dot matrix as well as display the design on the blink and provide notifications that occur at that time.
