An Intelligent Air Pollutant Vechicle Tracker System Using Gas Sensor and Gps

In p r es e nt d a y mod e r n wor l d Vehicles have become an part and parcel of every one's life. Situations and circumstances have their predominant role in the usage of vehicles in this modernized urban life. As to consider both sides of the coin, this has its own effects, one of the main side effects being air pollution. Each and Every vehicle will have emission but the main problem occurs in the case when it is beyond the standardized values fixed by the pollution control board of India. The main reason behind t h i s breach of emission level being the incomplete combustion of fuel supplied to engine, which is due to the improper maintenance of vehicles. This emission from vehicles cannot be completely avoided but, it definitely can be controlled. With the evolvement of semi-conductor sensors for detecting the various gases, this paper aims at using those semi-conductor sensors at the emission outlets of vehicles which detects the level of pollutants and also indicates this level with a meter. When the pollution/ emission level shoots beyond the already set threshold level, there will be a buzz in the vehicle to indicate that the limit has been breached and the vehicle will stop after a certain period of time , a cushion time given for the driver to park his/her vehicle. During this time period, the GPS starts locating the nearest service stations. After the timer runs out, the fuel supplied to the engine will be cut-off and the vehicle has to be towed to the mechanic or to the nearest service station. The synchronization and execution of the entire process is monitored and controlled by a micro controller. This paper, when augmented as a real time project, will benefit the society and help in reducing the air pollution. Keywords— Air Pollution, Sensors, threshold level, GPS, Micro Controller.
