How to Use an Ultrasonic Sensor for Object Detection

Introduction: How to Use an Ultrasonic Sensor for Object Detection

About: #BnBe is a platform to help teach electronics no matter what the age or skill level. We’re currently designing a wide range of products from beginner level kits to industry-standard microcontroller platforms.

After getting an understanding of how IR sensors work, we now learn about ultrasonic sensors. These have a much higher detection range and can be used for various purposes - from simple object detection to mapping surroundings. This post gives you all the information you need to know in order to use them and we also test it out by writing a demo Arduino sketch.

Step 1: Watch the Video

Since this is mainly a tutorial video, I'd recommend that you watch the video above to get a better understanding of using the ultrasonic sensor.

Step 2: Wire the Sensor

Connecting the sensor to the Arduino is extremely straight forward. Make sure you use a 5V Arduino board and connect it as shown in the reference wiring diagram above.

Step 3: Download the Sketch

You can download the demo sketch using the link below:
