This project focuses primarily on developing a .vi in labview to output a signal which is bounced off an object to determine a distance with the use of low cost transducers.

Defined- A transducer is a device that transmits power of one source into power of another. Transducers used in echo sounding are properly known as electro acoustic transducers since they convert electrical power and vice versa.
The lower frequencies have less power loss and are used for deep soundings, and since the beam angles are apt to be wider, thus more suited to observe or view a larger area For this project 40khz transducers were used.

 

Uses- Trasnducers have typically been used for such processes as remote sensing, and detecting distances. For this project the transducer was used to convert the short energy pulse into a sound wave that would bounce off the object be reconverted into an energy pulse and then the time calculated.
