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.
