Interfacing Ultrasonic Sensor with Arduino Uno

In this tutorial we will learn about integrating HC-SR04 ultrasonic distance sensor with Arduino Uno. Ultrasonic sensors are commonly used for obstacle detection and distance measuring applications. The sensor works on the same principles of a radar system, which converts electrical energy into acoustic waves and vice versa. The HC-SR04 ultrasonic sensor is based on the principle of SONAR, which is an abbreviation of Sound Navigation Ranging. This sensor is used in many hobby projects where there is a need...

Interfacing Ultrasonic Distance Sensor : ASCII Output with PIC Microcontroller

In some of our projects, we may want to measure the distance of an object from a point. Ultrasonic Distance Sensors are the best sensor which provides stable, accurate, precise, non-contact distance measurements from 2cm to 4m. Ultrasonic Sensors can be used to measure distance between moving or stationary objects. Being very accurate and stable, these devices find large number of applications in robotics fields. For example it can be used as an excellent replacement for IR sensors in a Micromouse. In...

Ultrasonic Sensors

Ultrasonic Sensors are widely used for non-contact proximity, presence and distance measuring applications. These devices work on a similar principle of sonar or radar which evaluates the target by interpreting the echo from sound or radio waves. It emits a short high frequency sound waves and evaluates echo which is reflected back from the target. Sensors uses the time interval between sending the sound waves and receiving the echo to determine the distance of target. Most of the ultrasonic sensors are equipped with temperature compensation circuit to avoid...
