Abstract: This study shows the construction of a compact pollution monitoring system designed to measure the percentage of the gases that escape from the cylinder, like oxygen (O₂) and carbon dioxide (CO₂). These are harmful to the environment, so to reduce the percentage of pollution of air through the escape gases, a custom-built filter/catalytic converter chamber is used. In this system, for interpreting exhaust gas data, the Arduino Nano microprocessor was used to display the gas proportion in real time on the 16 x 2 LCD screen. When the level of exhaust gases exceeds the predetermined safety threshold value level, an audible siren notifies the operator, and a 10-minute countdown timer starts as a warning. If the excessive CO₂ condition persists beyond this duration, the system automatically disconnects electricity to terminate operation, thereby preventing potential risks. This prototype demonstrates useful applications in environmental safety and emission regulation by providing an affordable, real-time solution for monitoring and managing emissions from small engines or laboratory exhaust.
