PROJECT DESCRIPTION

The project is designed to measure the distance by means of ultrasonic transducer sound reflection. Ultrasonic means of distance measurement is convenient method compared to the traditional method using measurement scales. This kind of measurement is particularly applicable to inaccessible areas wherein traditional means cannot be implemented, such as high temperature and pressure zones.

This proposed system uses an ultrasonic module interfaced to the microcontroller of the 8051 family. An ultrasonic transducer comprising a transmitter and receiver are used for the project. The transmitted waves are reflected back from the object and received by the transducer again.

The total time taken – from sending the waves to receiving back at the transducer – is calculated by taking velocity of the sound into consideration. Then, the distance is calculated by running a program on the microcontroller and is displayed on an LCD screen interfaced to the microcontroller. The ultrasonic sensor produces 40 kHz sound waves.

Furthermore, this project can be enhanced by using high frequency transducers to make it fit for medical applications like ultrasound machine.
