Abstracts: In summer, the temperature inside a car can rise up to 30 oC more than the outside temperature and pose a serious threat for children or pets left in the car, when it is parked outside. The increase in temperature of the car cabin is due to various modes of heat transfer such as conduction, convection and radiation. However, radiation along with the absorption is the main cause of this dramatic rise in temperature. This project mainly focuses on regulating the internal temperature of the car. A new ventilation system has been designed that employs exhaust fan and blower, temperature sensors and electronic control circuit which control the temperature inside the car cabin even though ignition system is off. Experimental investigation will be performed on a proto-type model placed under direct sun light to study temperature difference between car cabin and atmosphere. Furthermore, experiments will be done on a prototype of a car-cabin, which will be designed and fabricated based on the simulation performed using solid model. Two experiments will be conducted at different ambient temperature and smart system activation temperature can be find out. It is aimed that the temperature inside the car will drop significantly when the smart ventilation system will be activated
