Car indoor gas detection system

Thousands of people are dying because of breathing Carbon monoxide (CO) gas every year. In terms of poisons history, it has more unintentionally deaths than any other ones. One of the main resources of generating CO is fuel. Number of vehicles that use LPG are increasing dramatically. Technical problem in LPG injection system sometimes will result in irreversible effects for driver and passengers. At the other hand many people especially in cold climate countries are travelling in winter with their own vehicles. In most cases many of people who their cars getting stuck in the snow, stay inside the car waiting for help. In this situation if the exhaust is blocked by snow or any other resources, the CO enters the car cabin and passengers without being noticed are died. In this paper, we introduce a system by using Arduino that is able to measure CO level, make warnings for driver and send vehicle's geographic coordinate along with warning messages for defined telephone numbers in emergency situations.
