Ultrasonic sensor (HC-SR04) is commonly used to find the distance of an object from one particular point. It has been fairly easy to do this with the Arduino and the code is also pretty simple. But in ...

In this project we are going to discuss how to use Ultrasonic sensor ... upload the sketch to the Arduino. Once uploaded to the Arduino, open the serial monitor, and you should see the distance data ...

Calculating normal distance with the HC-SR04 ultrasonic sensor in the 3 Pin Mode and an Arduino UNO board: Calculating precise distance with the HC-SR04 ultrasonic sensor in the 3 Pin Mode, a DHT ...

There is the infrared sensor, which uses the properties of light to calculate distance, and the Arduino ultrasonic sensor uses the properties of sound propagation to measure distances. More ...

Inside [Klaus]’ device is an Arduino Uno, an HC-SR04 ultrasonic distance sensor, and an Adafruit Wave Shield. Originally, this parking/distance sensor used a small TFT to display the distance to ...

This is an Arduino-based Proximity Sensor circuit wired using the popular HC-SR04 Ultrasonic ranging module,used here for non-contact object detection purpose. The HC-SR04 module includes ultrasonic ...
