Abstract – Abstract – Many times cars heat up more than the environment temperature when they parked in the sun. When the temperature increases outside, cars become a hazardous place, especially for children, the elders, and pets. That is because a car’s cabin environment augments very fast, even when it is parked in the shade. According to our research on average, a number of children under the age of 16 have to suffer from heatstroke each year because they were left in a hot car. Besides, leaving children and pets in hot cars is illegal in more than 25 states including California, Texas, Florida, and Illinois. To solve this problem, we have designed the “ Legroom Vaccum System”. Which can reduce the internal temperature of cars by 60-70% by installing Automatic Exhaust. The heat exhaust system at each and every Doors also called the “Legroom Vaccum System”
many problems such as environmental pollution, and traffic congestion affecting human and pet’s physical and mental health. Studies found that outdoor car parking under the sunlight augments the inner cabin temperature by 60 degrees. The hot temperature inside the car absolutely makes the driver feel uncomfortable in the first 5-10 minutes.

1. INTRODUCTION
2. Temperature variation inside and outside
The major difficulty to overcome in the development of the “Legroom Vaccum system” is to design and develop a system that can monitor the temperature and change the cabin environment according to the requirement. Therefore, we purchased a temperature controller and install it in our existing system. A W1209 DTC (Digital Temperature Controller) is used to control the heat inside the cars or other important equipment by comparing a sensor signal which is set at maximum and minimum points and perform on calculations according to the deviation between those values. Pieces of equipment that can handle sensor signals for temperatures, like humidity, pressure, and flow rate, are called Controllers. Further, we designed our model with the help of different designing software like AutoCAD, Solidworks, and Fusion360. Now we required all the equipment for the assembly process like low voltage exhaust motors which can give excellent output power, Aluminum nets, 12v Li-ion battery, and so on. In addition, the number of privately owned vehicles has suddenly increased and national car projects also have played a role in motor vehicle growth by limiting the options available to the government. An increasing number of public and private transportations generates

The sun generates energy in the form of wave radiation, which goes through the glass of a car window, or roof of the car and heats up cars. The sun's wave radiation is absorbed by the surfaces of the car such as the roof, the dashboard, and the Glass, and so on. These surfaces in the car then re-radiate the energy, but in the form of infrared radiation, that heats up the air inside the car. Since the windows are closed, the air circulation is closed in the car. Longwave radiation can't leave through windows as shortwave radiation. The heat gets caught inside the car, just like the Greenhouse Effect. The temperature changes from cool to hot within a minute inside the car. ISO 9001:2008 Certified Journal
