HC-SR04 Ultrasonic Distance Sensor with Arduino (5 Examples

  1. Ultrasonic sensors work by emitting sound waves with a frequency that is too high for a human to hear. These sound waves travel through the air with the speed of sound, roughly 343 m/s. If there is an object in front of the sensor, the sound waves get reflected back and the receiver of the ultrasonic sensor detects them
  2. VCC is the power supply for HC-SR04 Ultrasonic distance sensor which we connect the 5V pin on the Arduino. Trig (Trigger) pin is used to trigger the ultrasonic sound pulses. Echo pin produces a pulse when the reflected signal is received. The length of the pulse is proportional to the time it took for the transmitted signal to be detected
  3. This video is about using the popular HC-SR04 Ultrasonic Sensor with an Arduino Uno to make distance measurements. You can use these measurements in many applications from robot object avoidance.
  4. Ultrasonic sensors work by sending out a sound wave at a frequency above the range of human hearing. The transducer of the sensor acts as a microphone to receive and send the ultrasonic sound. Our ultrasonic sensors, like many others, use a single transducer to send a pulse and to receive the echo

So an ultrasonic sensor, also known as ping sensor is commonly used to measure the distance of an object from its surface by emitting and receiving sound waves. The transmitter transmits the sound waves whereas the Receiver receives these transmitted sound waves reflected back from the object Measures the travel time of the ultrasonic wave. Ultrasonic sensor: generates a pulse to the ECHO pin. The duration of the pulse is equal to the travel time of the ultrasonic wave. Micro-controller measures the pulse duration in the ECHO pin, and then calculate the distance between sensor and obstacle

Ultrasonic sensors are used around the world, indoors and outdoors in the harshest conditions, for a variety of applications. Our ultrasonic sensors, made with piezoelectric crystals, use high frequency sound waves to resonate a desired frequency and convert electric energy into acoustic energy, and vice versa. Sound waves are transmitted to and reflected from the target back to the transducer. Ultrasonic level sensors use the Time-of-Flight measuring principle to measure level. The device sends sound waves at a frequency higher than humans can hear, from 20 kilohertz to one gigahertz. These waves bounce from the surface of the product, creating an echo that goes back to the sensor. Then, the sensor calculates the time the echo took to return to find out the level. It works in both.
