Automobiles have become an indispensable element of everyone’s daily life. In today’s fast-paced urban environment, circumstances often necessitate the use of personal vehicles. However, just as every coin has two sides, the widespread use of automobiles brings its own consequences—one of the most significant being air pollution. Although all vehicles produce emissions, the problem becomes severe when these emissions exceed established limits.
A major cause of this violation of emission standards is the incomplete combustion of the fuel supplied to the engine, which often results from poor vehicle maintenance. With advancements in semiconductor sensors capable of detecting various gases, this research proposes using such sensors at vehicle emission outlets to monitor pollution levels. The system will display the emission levels on a meter, and when pollution exceeds a predefined threshold, the vehicle will emit a warning buzz. After a specified period, the vehicle will automatically come to a halt, allowing the driver to safely park. When the timer expires, the system will cut off the engine’s fuel supply, requiring the vehicle to be towed to a mechanic or service station.
This solution incorporates Internet of Things (IoT) technology—an integration of computer science and electronics. In this system, embedded computing is coupled with sensing devices to enable real-time monitoring and control of vehicle emissions.
