Vehicles are the mode of transportation in our day to day life. Considering four wheelers, six and many more heavy vehicles, it is quite a difficult job for the driver to have a glance on the four sides of the vehicle, which is one of the cause for road accidents that leads to major damage to the vehicles and even severe injuries to the occupants of the vehicles. When the vehicle is at rest position there were many chances for the pets to go under the vehicle and also some obstacles like rocks may exist under the vehicle. When the driver starts the vehicle he/she will never have a look under the vehicle which may cause damage to the vehicle and nudging of pets which may lead to their death. This project is designed to overcome the above problems Raspberry Pi and Ultrasonic sensors are used to monitor the presence of obstacles around and under the vehicle. The distance monitored is displayed on user interface. An alert is provided to the driver when the obstacle or any other vehicles are nearer to the vehicle. This system also monitors the obstacles under the vehicle and shows a message on the user interface regarding the presence of an obstacle under the vehicle. This helps the driver to drive accordingly and to have control over the vehicle which assures a safe drive.
