The purpose of this project wax to aware students of engineering about the working and application of the Arduino and sensors. These instrumentational tools play a vital role in construction of integrated and complex real-life systems. We used ultrasonic sensor along with a microprocessor (Arduino) to measure distance of the object in range of the particular sensor. We coded our microprocessor to work for the particular application. As a result, we were able to measure critical distance which as an application will be used as parking warning device. Nowadays, we have some difficulties in obtaining the distance that we want to measure. Even. though, measuring tape is an easy option, but this kind of tool will have a limitation of manual error. Before this, engineers. have produced a range finder module but, in the end, they find out the module have many disadvantages like limitation for distance, different result for different coloured obstacles, and need a calibration for every time before starts using it. Manual distance measuring is always done at the expense of human error.
