        abstract = {The rise in air pollution levels poses serious threats to human health, the environment, and industrial safety. Monitoring the presence of hazardous gases in real-time has become essential to ensure a safe living and working environment. The Multi Gas Air Detection System with Visual Feedback is designed to detect and display the concentration levels of multiple harmful gases in the surrounding air using an efficient and cost-effective setup. It interfaces with various MQ series gas sensors to monitor gas concentrations continuously. These sensors provide analog signals proportional to the gas levels, which are processed by the ESP32. For real-time visualization, the system uses an I2C OLED display (128x64 resolution) to show gas concentration values in parts per million (PPM). Additionally, the system provides visual feedback using color codes or warning icons on the display to indicate air quality status, ranging from safe to hazardous levels. Thresholds are programmed to alert users when dangerous concentrations are detected.},
