This paper represents advanced co2 sensing device in vehicle. This system is used for sensing co2 level in vehicle and
actuating the oxygen pump if the level of co2 goes high by sensing message. Main function of this system is to alert the person
about the co2 level in the vehicle. Modern growth and economic transformation of Indian society resulted in increased vehicle
and passenger health issues. The aim of the present study is to develop a system that will make car rider safer. In this system we
basically focus on the safety of passengers in the vehicle. It has modern GSM chip system which sends the message to the owner
of the vehicle that the level of co2 in their vehicle is increasing. Also in high altitudes the oxygen level in atmosphere decreases
rapidly and therefore breathing problem like suffocation, nasal congestion may take place. To eliminate these problems in vehicle at high altitudes, when co2 level increases beyond the limit this system immediately sends the message and starts the oxygen
pump.
