Abstract -Air quality monitoring is very important, not only in general, but of course in urban and industrial areas, where being on the part of pollution that is one of the problems that is growing. It is on the bases of that, research in this case is presented in the design and implementation of a smart air quality monitoring system using the IoT technology. The wireless connects along with the DHT11 sensor for temperature and humidity reading and MQ-135 gas sensor module to sense various air pollutants including CO2, CO & VOC. The Blynk app is used to analyze and visualize data in real time, with users able to have an intuitive user interface of the air quality trend. The system was tested under different weather conditions and was found to deliver reliable and accurate feedback of air quality. It also provided real time feedback for users through a serial monitor. The results indicate successful integration between hardware and software components and the Blynk app provides a relatively user-friendly way of displaying, analyzing and interacting with the data output from the sensor. However, the current study demonstrates the feasibility of IoT based air quality monitoring systems for real time environmental monitoring. Future efforts will focus on improving system accuracy; improving sensor calibration; and the development of more capable large scale, urban air quality monitoring application.
