This document describes a system to monitor sound levels using an IoT device and display the results. A sound sensor measures noise intensity and sends the data to a NodeMCU microcontroller via WiFi. The NodeMCU then uploads the real-time data to a cloud database and displays it on a local LCD screen. The system can detect low, moderate, and high noise levels and activate different colored LEDs and a buzzer accordingly. The cloud database allows monitoring sound levels remotely from any location. The system is intended to help control and monitor noise, especially in industrial areas.
