M.A.R.S - Mechanized Air Refilling System

Every section of an automobile is getting automated except one- Tires. To inflate a tire, the driver has to go to a gas station or he has to attach a pump manually. Both these involve human labor. This project is aimed at removing such unwanted strain and save time. The system has a dedicated unit for filling air whenever required. A control unit which is a pic microcontroller is the brain of the system. When the pressure level is below the threshold value chosen by the driver, the system displays it. The driver then may choose to refill the air automatically. A compact pump does the job. Another problem in tires is a puncture. A sudden puncture can cause the driver to lose control, culminating in an accident. The project’s minor objective revolves around this. During a puncture the air pressure reduces suddenly. This reduction in pressure over a time limit is identified as a puncture. It warns the driver of a puncture and saves life. The other way of detecting a puncture is by calculating the ON time of the pump. If the pump is in ON state for a long time and there is no improvement in the pressure level it is recognized as a puncture. It also saves a lot of money by giving more longevity to the tire and better mileage. As the tire is filled with optimum air, the friction between the tire and the road is maintained properly. Henceforth, the tire is not damaged much and the fuel consumption is reduced. The project is destined to be a life and money saver.
