ABSTRACT
The project is designed to measure the
distance of any object by using an ultrasonic transducer. Ultrasonic means of
distance measurement is a convenient method compared to traditional one using
measurement scales. This kind of measurement is particularly applicable to
inaccessible areas where traditional means cannot be implemented such as high
temperature, pressure zones etc.
This proposed system uses an ultrasonic
module interfaced to a microcontroller of 8051 family. An ultrasonic transducer
comprising of 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 it is
calculated by taking into consideration the velocity of sound. Then the
distance is calculated by a program running on the microcontroller and displayed
on an LCD screen interfaced to the microcontroller. The ultrasonic sensor produces
40 kHz sound waves.
Further the project can be enhanced by using
high frequency transducers to make is fit for medical applications like
ultrasound machine.
