Embedded System Based Air Pollution Detection in Vehicles

Abstract: Air pollution is one of environmental issues that have been often discussed. A system is developed to reduce air pollution. The proposed system consist of carbon monoxide (CO) sensor, liquid petroleum gas (LPG) sensor, buzzer, global positioning system (GPS), global system for mobile (GSM). CO sensor is placed at the emission outlets of the vehicle to monitor the level of CO emission, LPG sensor placed near gas supply pipe of the vehicle to detect LPG leakage. The buzzer in the system alerts, when the emission level or leakage of gas exceeds threshold value. The GPS finds current location of the vehicle and transmit to the microcontroller. The entire process controlled and monitored by ATmega328 microcontroller. The microcontroller search for nearest service station by comparing with already stored locations in the memory. GSM sends service request message to nearest service stations. The proposed novel system helps in reducing the air pollution
