Ultrasonic sensor, also known as a SONAR sensor is an electronic device that is used to measure the distance of a target object by emitting ultrasonic sound waves. Apart from distance measurement, it ...
It emits an ultrasound at 40 000 Hz which travels through the air and if there is an object or obstacle on its path It will bounce back to the module. Considering the travel time and the speed of the ...
This project implements a rotating ultrasonic distance scanner using an Arduino, an HC-SR04 ultrasonic sensor, and an SG90 servo motor. Distance readings are transmitted over serial and visualized in ...
