The monitoring and detecting the vehicle, which is polluting our atmosphere is becoming a major problem in many countries. With the ever increasing number of vehicles on the road, the Traffic Monitoring Authority has to find new methods of overcoming such a problem. Considering that the transport sector is responsible for an increasingly important share of current environmental problems, we look at Intelligent Transportation Systems (ITS) as a feasible means of helping in solving this issue. In the system proposed, we detect the vehicle, which is polluting our atmosphere is identified through a compact circuitry comprising of PIC16f877a controller, CO2 sensor, GPS and GSM. The CO2 sensor is used to detect the how much gas released by the vehicle. In controller we fixed some threshold value from that controller identify the abnormality, then send the warning message to the user. If till abnormality is increase then controller track the location using GPS and send the information to the user and also engine (motor) is switch OFF. This system is a realistic concept and can be applied to automatic vehicles emission testing.
