Measuring Distances With an Ultrasonic Sensor Using Arduino

Measuring Distances with an ultrasonic sensor using Arduino Abstract Measuring distances automatically and continuously comes in handy in many situations. Think of a robot that autonomously tries to find its way or of an automatic burglar alarm that rings a bell, this is possible with Arduino. Many different types of sensors for measuring distances are available, and the Arduino plays well with most of them. Some sensors use ultrasound, while others use infrared light or even laser. In this project, we will build a device that measures the distance to the nearest object and outputs it on the serial port. For this project, we use the Parallax PING))) ultrasonic sensor,2 because it’s easy to use, comes with excellent documentation, and has a nice feature set. It can detect objects in a range between 2 centimeters and 3 meters, and we use it directly with a breadboard, so we do not have to solder. It’s also a perfect example of a sensor that provides information via variable-width pulses.

Abstract
Measuring distances automatically and continuously comes in handy in many situations.

Many different types of sensors for measuring distances are available, and the Arduino plays well with most of them. Some sensors use ultrasound, while others use infrared light or even laser.
In this project, we will build a device that measures the distance to the nearest object and outputs it on the serial port.
