Digital Measuring Tape

Abstract

Nowadays, all kinds of measurements require human aid in one form or the other for the
accurate measurements to be performed, until the proposal of this device. The proposed
device ultrasound sensing technology that transmit ultrasonic waves and receive them with
the ability to output the time delay between the transmission and reception of the ultrasound.
Hence using this method, one is able to measure the distance between two objects without
physical means of measurements. The device automatically calculates the distance as per the
programmed code and displays the distance measured in meters. The SI unit can be changed
if needed for more precision.
