Paper Title
Air and Sound Pollution Monitoring System

Abstract
This paper develops and evaluates a method for monitoring air and noise pollution. The technology is entirely based on the technology of the Internet of Things (IoT) and is extremely useful in the field of pollution management. Over time, we can track the level of pollution (air or sound) in this system. The basic components of the proposed system, such as IoT components and their operation, Microcontroller (NodeMCU) and its architecture, Gas sensor and its features, Sound sensor and its specifications, and ESP8266 Wi-Fi Model, are discussed in detail in this article, as well as the modeling and operation of the basic components. Keywords - Pollution, Systems engineering, Control systems, Wireless network, Communication system, Node Mcu, Buzzer, LCD, Arduino IDE, LED, IoT.
