Abstract

Air pollution is a major concern as it directly affects human health, leading to serious illnesses and, in some cases, premature death. It also has economic consequences, including increased healthcare costs. To address these issues, this research presents the design and development of a portable air quality detector utilizing Internet of Things (IoT) technology. The device, controlled by the NodeMCU ESP8266 microcontroller, provides real-time air pollution data to users, enabling continuous environmental monitoring. The detector categorizes air quality into five levels, ranging from good to poor, using a color-coded system: green, yellow, orange, red, and purple. It measures key environmental parameters, including particulate matter (PM2.5), temperature, humidity, carbon dioxide (CO₂), total volatile organic compounds (TVOCs), and Ozone (O₃), displaying real-time color-coded alerts to inform users about air quality conditions. Additionally, integration with the Blynk application allows for remote monitoring, enhancing the device’s usability and practicality. This air quality detector serves as an effective tool for individuals, households, and workplaces to monitor environmental conditions, take preventive actions, and promote healthier living environments.
