There are several ways of contactless distance measurements. This research work made use the principle ultrasonic measurements and calculations as well tracking dynamic object by techniques comparison. When an electrical pulse high voltage is applied to transducer it vibrates across a specific spectrum frequencies generates burst sound waves. Each time any obstacle comes ahead sensor, waves wil...
