Vehicles became important in human life. This air pollution mainly caused by vehicles and industries. This paper mainly concentrated on controlling the air pollution from vehicles by using semi-conductor gas sensor for detecting the emission level from vehicles. If the vehicle do not get service regularly, then pollution level higher than standard emission level. In this paper, smoke sensor has been used to detect carbon monoxide from vehicles. Smoke sensor senses the pollution level from vehicles. If pollution level is recorded beyond the standard values from government, then microcontroller alerts the buzzer and displays pollution level on LCD.
