Design and Construction of a Smart Multi-Directional Ultrasound Detector

Abstract

Ultrasound is inaudible to the human ear, hence a means of effective and accurate detection is necessary. In this work, an electronic device that is capable of searching, identifying and recording the instantaneous status and direction of ultrasound within the vicinity was developed. The device is made up of the following sections power, sensing, amplification, comparison, control and output. These sections work in synergy to give precise detection and direction of ultrasound. The device is also equipped with a 360" scanning mechanism which enables it pick faint ultrasonic signal, amplifies it via a series of op-amps, calibrate its readings and display the result
