Automatic PUC Detection using GSM

The exponential growth in vehicle population and the dominance of old vintage vehicles on Indian roads make the issue of inspection and maintenance a prime concern in India. In the last decade, several aggressive initiatives to control vehicle pollution have been taken in India but most of the steps are directed towards new vehicle emission norms and fuel quality improvements. In major cities there exist a mandatory system for inspection and maintenance but it is now increasingly felt to upgrade the present system to a more effective one in the near future. Motor vehicles are the prime source of transportation where vehicles with Petrol or Diesel play a major part. This project designs an embedded system for a vehicle, which senses the gases like carbon monoxide. If the level of the Carbon monoxide (CO) increases than the normal level (10 ppm to 100 ppm), then an alarm is generated automatically.
