Due to an enormous rise in the amount of time spent inside as a result of industrial growth, indoor air quality has emerged as a major issue in the preservation of human life. Public health experts, environmental regulators, and business experts are working to enhance the overall health, comfort, and well-being of building occupants. Even though ventilation and air purification systems are placed in several interior areas, the purity of the air cannot be guaranteed without effective monitoring systems. In the rapidly advancing world of technology, the integration of Internet of Things (IoT) devices has become increasingly common to enhance the capabilities of various systems. One such application involves the incorporation of an air quality monitoring system into a line-following robot. This system utilizes the DHT11 sensor for temperature and humidity measurements, the MQ-135 sensor for detecting air quality, an LCD display for local information, and the ESP8266 module for online connectivity through Blynk. In this study, we developed a smart indoor air quality monitoring device, measuring components of temperature, humidity, NH3, NOx, CO2, benzene, smoke, and other dangerous gases in the atmosphere. Using short and long-distance communication modules, the smart air quality monitoring system is connected to a built smartphone application to oversee the air quality in the area. As a result, the smart air quality monitoring system may be used to predict future air quality, which would help to enhance indoor air quality in real time.
