Abstract: - As the smart systemhas been developed in the automobile industries, new features are implementedfor the comfort of customer. However, if a car is locked, creating a closedcabin, the unaware toddlers and animals (pets), in the car, cannot open thedoor or windows. The closed car cabin may result in depletion of oxygen (O2).There are mainly two major reasons of suffocation: first, when a traveller getslocked in car and being unaware of the car system; and second, the other one iswhen the traveller is inside the car and the car gets locked due to indulgenceof water and engine. The other major problem, the youth is facing, is smokingin closed car which may result is a disaster.
Toovercome these problems the authors have suggested a system which will use theemerging technology, IoT. This will conquer the system (car) and human beingthrough Message App by sending electronic alert messaging through GSM modem.Hence, this proposed work deals with the safety of the traveller sitting in theclosed car cabin, and gives a safe exit in adverse conditions.
