Internet of Things Devices for Atmospheric Pollution Detection

Abstract

Air pollution is a major environmental and public health hazard due to the rise of industrialization and urbanization. In this project, we present an Internet of Things (IoT) system for detecting atmospheric pollution. The system can track the air quality in real-time using sensors such the MQ2 gas sensor and the DHT11 temperature and humidity monitor. Providing data in parts per million (PPM), the MQ3 sensor detects dangerous gases including carbon monoxide (CO) and methane (CH4), among others. Important variables in determining changes in air quality, the DHT11 sensor monitors both humidity and temperature. Internet of Things (IoT) integration allows for cloud-based pollution level monitoring and analysis from afar. To further guarantee prompt action and preventative actions, a buzzer is integrated to deliver an instant notification whenever pollution levels above a specified threshold. A safer and healthier environment is a result of this system's ability to help authorities, companies, and individuals make educated decisions about managing air quality.
