Abstract: In order to mitigate overheated interior of a vehicle parked in the hot summer sun and thereby to make the entering into the vehicle more comfortable, microcontroller managed module for automatic ventilation of vehicle interior is made. The module is implemented using a microcontroller as a central logical unit and a series of sensors which provide sufficient data to ensure functional, but also efficient, reliable and safe ventilation. The ventilation process is performed by opening vehicle windows slightly, which enables air to circulate. The PIC microcontroller controls the car head light system during the night time travel by controlling the high beam and low beam lights. The system is embedded with MATLAB which access the camera and monitors the position of driver face. It can avoid the accidents by alert the driver using alarm or by stopping the vehicle. This paper shows the components, their purpose and capabilities, advantages and disadvantages, as well as potential implementations and upgrades. The test results give insight into utilization options of this module and its usefulness.
