Project 2 - Measuring the distance of an object using ultrasonic sensor and also smoothen the sensor data using moving average filter

KKarthik S18 Aug 2022

Overview of the Project:

In this project the implementation of code for “Measuring distance of an object using ultrasonic distance sensor (28015 Ping) and also smoothen the sensor data using moving average filter”.

Goals:

Measuring the distance in terms of inches of an object using Ultrasonic Distance Sensor (28015 Ping).
The sensor data is smoothened by using Moving average filter technique to eliminate the high frequency variations from the sensor data.

Key Highlights of the Project:

Measuring the distance travelled by the wave to the object and gets bounced back from the object to sensor.
Smoothening the sensor data by moving average filter technique, the filter has a window of certain size. That window determines that how many data the filter can take.

Deliverables of this project:

The distance travelled by a wave to the object for which we want to measure the distance using Ultrasonic Distance Sensor (28015 Ping).
Eliminate the high frequency jitters from the sensor data by Moving Average filter to smoothen the sensor data.

Expected Outcomes:

The students will get the Knowledge on Ultrasonic sensor (28015 Ping) to measure the distance travelled by wave to the object, the hardware connection of 2 Arduino’s connected to the sensor and smoothening the sensor data by removing high frequency variations using Moving Average Filter Technique.

Question :

Measuring the distance of an object using ultrasonic sensor and also smoothen the sensor data using moving average filter

Answer :

The distance of an object using ultrasonic sensor., In this project the implementation of program for “Measuring distance of an object using ultrasonic distance sensor (28015 Ping) and also smoothen the sensor data using moving average filter”.

Program:

int trigPin = 11; // Trigger

int echoPin = 12; // Echo

long duration, cm, inches;

long sum=0;

long avg;

int i;

//serial communication

void setup()

{

//Serial Port begin

Serial.begin (9600);

//Define inputs and outputs

pinMode(trigPin, OUTPUT);

pinMode(echoPin, INPUT);

}

void loop()// The sensor is triggered by a HIGH pulse of 10 or more microseconds.

{

// Give a short LOW pulse beforehand to ensure a clean HIGH pulse:

digitalWrite(trigPin, LOW);

delayMicroseconds(5);

digitalWrite(trigPin, HIGH);

delayMicroseconds(10);

digitalWrite(trigPin, LOW);

// Read the signal from the sensor: a HIGH pulse whose

// duration is the time (in microseconds) from the sending

// of the ping to the reception of its echo off of an object.

pinMode(echoPin, INPUT);

duration = pulseIn(echoPin, HIGH);

// Convert the time into a distance

cm = (duration/2) / 29.1; // Divide by 29.1 or multiply by 0.0343

inches = (duration/2) / 74; // Divide by 74 or multiply by 0.0135

for (i=0; i<5; i++)

{

sum=sum+inches;

avg = sum/5;

}

Serial.print(avg);

Serial.print("Avg, ");

Serial.print(cm);

Serial.print("cm");

Serial.println();

Serial.print(inches);

Serial.print("in");

Serial.println();

delay(250);

}
