Story

In this simple project, we introduce the Interfacing Ultrasonic Sensor with Arduino. But what are those Ultrasonic sensors ?

Ultrasonic sensors are used to send and get ultrasonic pulses that in turn share information about an object’s proximity

There are many applications for using Ultrasonic Sensor such as:

Presence detection

Sorting boxes using a ultrasonic monitoring system powered by multiple transducers Bottle counting on drink filling machines

Pallet detection with forklifts

People detection

Profiling using ultrasonic systems

Vehicle detection for car wash and automotive assembly

Liquid level control / tank level control

Loop control

Tension control

Robotic sensing

Stacking height control

Detecting thread or wire breaks

Code

Code

#define trigPin 13
#define echoPin 12
#define led 11

void setup()
{ Serial.begin (9600);
pinMode(trigPin, OUTPUT);
pinMode(echoPin, INPUT);
pinMode(led, OUTPUT);
}

void loop()
{ long duration, distance;
digitalWrite(trigPin, LOW);
delayMicroseconds(2);
digitalWrite(trigPin, HIGH);
delayMicroseconds(10);
digitalWrite(trigPin, LOW);

duration = pulseIn(echoPin, HIGH);
distance = (duration/2) / 29.1;

 if (distance < 50)

{ digitalWrite(led,HIGH);
}

else {
digitalWrite(led,LOW);
}

Serial.print(distance);
Serial.println(" cm");
delay(500);
}
