A Survey of Ultrasonic Sensors and their Applications

Abstract: The aim of this document is to provide detailed information on some of the readily available ultrasonic sensors. It also explains the working principle of the sensors and how they are implemented. Finally, we look at a few applications of these sensors along with a decision making guide. This document will help any reader wanting to learn about ultrasonic sensors and deciding which one suits their application’s need.
