Tutorial-3 Ultrasonic sensor Interfacing with Arduino In Advance level
Introduction : SONAR basically stands for Sound Navigation and Ranging. Ultrasonic is mostly used for the distance measurement prototype applications. It can also be used for measuring the depth of the sea. Ultrasonic/SONAR sensor is an electronic device used to estimate the distance of an object by continuously transmitting sound waves at a particular frequency and listens to that transmitted sound wave to bounce back. It measures the time between the transmission and receiving of that sound wave, which is actually equal to the distance of an object from the SONAR. An optical sensor has both a transmitter to transmit and a receiver to receive the waves. But in comparison to that optical sensor ultrasonic sensor has only a single element for both transmitting and receiving ultrasonic/sound waves. Here i share ultrasonic sensor interfacing and its advance level applications designing like street light controller, vehicle parking systems. Table of Conte
