Abstract

The global challenge of environmental air quality monitoring necessitates the development of innovative solutions. In response, a novel intelligent system was designed to monitor air quality through the integrated analysis of gases (carbon dioxide, carbon monoxide, and liquefied petroleum gas), room temperature, and humidity, utilizing the Arduino microcontroller and the Internet of Things application. The initial phase involved rigorous component selection, including the Arduino microcontroller, gas sensors, Wi-Fi module, humidity and temperature sensors, LCD display, buzzer, and communication with the Blynk application. Subsequently, seamless integration of these electronic components of the system and envelopment of the prototype in acrylic material were accomplished. After envelopment, the system was then deployed for integrated environmental monitoring of gases, temperature, and humidity. The results showed that the developed system exhibits a cost-effective and high-performance solution, characterized by its compactness, practicality, and versatility in various environments. Its implementation costs are significantly low, making it commercially viable.
