Abstract: Prior research is to establish a connection with OBD of a vehicle which provides vehicular connectivity with smartphones using internet for existing vehicles that don’t have an inbuilt vehicular connection and adds an additional sensor units which are not present making it easy to monitor all the systems in the vehicle. Most vehicles that are on roads don’t have this technology and this is mostly found in expensive cars. Using the proposed system, such vehicular connection system can be installed separately at a cheaper expense in all vehicles. Through this, the status of the vehicle is diagnosed by the OBD system and the report is transferred to the laptop in the GUI. Using the system, additional sensors can be added to a vehicle to upgrade its functionality, which the system supports. Additionally, driver assist functions are introduced, helping the driver during the travel period. Here our main motive is to provide the same comfort and features that has been introduced in the recent top end module vehicles. By ensuring that, it should be cost effective, long lasting and user friendly at the same time. This could be made possible for daily transportation like metro, services, public transportation, mid variant vehicles in car and busses. This can be achieved by introducing On-board Diagnostic system protocol over a control area network to scan and collect the data from the vehicle subsystems and feed this data to the display by means of USB connection which makes easier to visualize graphical represented data in a pc through a Graphical User Interface. The expected output for this design would be the wiper should get on when the sensor in it recognises the rain droplets and turn on the LDR automatically as the rain could lead to fog and mist and these particles also have been recognised by the wiper or LDR. The continuous monitoring of the tyre pressure and reflecting the values of each to the dash board so that user could know if there is dangerous fall in the tyre pressure and could be able to stop the upcoming accidents or discomfort. These all have been done through the software implementation, here we are using python to support our code. The hardware connection should be made ready to dump the code supported by python to make
