Hi Friends, Today In This Article,  i Will Show You How To Make DISTANCE METER WITH ARDUINO.

as we know the Ultrasonic sensors are great tools for measure distance and detect objects  , In this project, we have used the HC-SR04 Ultrasonic Sensor with Arduino and Oled Display to determine the distance of an obstacle from the sensor.

WHAT IS AN ULTRASONIC SENSOR?ultrasonic sensor to make DISTANCE METER USING ARDUINO

An ultra sound sensor is a device for measuring distances . Its operation is based on the sending of a high frequency pulse, not audible by the human being. This pulse bounces off nearby objects and is reflected back to the sensor, which has a suitable microphone for that frequency.

By measuring the time between pulses , knowing the speed of sound, we can estimate the distance of the object against whose surface the ultrasound pulse hit

Ultrasonic sensors are cheap sensors, and easy to use . The theoretical measurement range of the HC-SR04 sensor is 2cm to 400cm, with a resolution of 0.3cm. In practice, however, the actual measurement range is much more limited, around 20cm to 2 meters.

HOW DOES AN ULTRASONIC SENSOR WORK?

How HC-SR04 Ultrasonic Sensor Works

The sensor is simply based on measuring the time between sending and receiving a sound pulse . We know that the speed of sound is 343 m / s in conditions of temperature 20 ºC, 50% humidity, atmospheric pressure at sea level. Transforming units results

Distance= (Time x Speed of Sound in Air (340 m/s))/2

Code for Distance Measurement

The complete code for this distance measurement project is given at the bottom of this page.  In the code we read time by using pulseIn(pin). And then perform calculations and displayed result on the  OLED display .
