Abstract

The noise level in the room is one of the factors that can influence teaching and learning activities. Research on classroom noise levels has been done using the Wemos D1 R1-based KY-037 sound sensor. This research aims to determine the noise level in the classroom and be able to monitor the noise level in the room. Data collection was carried out by sound detection in the classrooms of SMA Negeri 13 Palembang from 07.00 – 12.00 WIB for seven days. The research results show that the system is functioning well, indicated by the situation when the noise level is less than 45 dB, and the LED lights up. When the noise level is more than or equal to 45 dB, then the yellow LED, mini DFPlayer, and speaker will light up, and when the noise level is more than or equal to 55 dB, then the red USB LED, mini DFPlayer, and speaker will light up. Data on noise levels and LED conditions received can be monitored via the web server. The system used on the web server is localhost access on a computer that can be monitored within the school environment.

使用基于 Wemos D1R1 的 KY-037 声音传感器设计教室噪音监测工具

室内噪音水平是影响教学活动的因素之一。我们使用基于 Wemos D1 R1 的 KY-037 声音传感器对教室噪音水平进行了研究。这项研究旨在确定教室内的噪音水平，并能够监测教室内的噪音水平。数据收集是通过声音检测在巴伦邦 SMA Negeri 13 的教室中进行的，时间为 7.00 - 12.00 WIB，为期 7 天。研究结果表明，当噪音水平低于 45 分贝时，LED 灯亮起，表明系统运行良好。当噪音水平大于或等于 45 dB 时，黄色 LED、微型 DFPlayer 和扬声器会亮起；当噪音水平大于或等于 55 dB 时，红色 USB LED、微型 DFPlayer 和扬声器会亮起。可通过网络服务器监控接收到的噪音水平和 LED 状态数据。网络服务器使用的系统是本地主机访问计算机，可在学校环境内进行监控。
