Example project: 

 

HC SR04 Distance Measurement Tool
 

This article will demonstrate how to build a simple distance measuring device using the HC SR05 ultrasonic sensor board. This project can be used standalone as a way of measuring short distances or, it can be incorporated into other projects that require distance measuring. This sensor works best when the two transceivers are parallel to a solid surface, at a distance between 2cm to 450cm. 

 

Here’s what you will need:

 

Tools

Jumper leads – Male to Female x 8

Breadboard (optional)

Components

HCSR04 Ultrasonic Distance Sensor x 1

Arduino Uno x 1 or Arduino Nano x 1

LCD1602B LCD Screen x 1

KY1602 Parallel to Serial Converter x 1

 

Libraries

LiquidCrystal I2C

HCSR04 ultrasonic sensor

 

Step 1

First, you will need to connect the HCSR04 sensor to the Arduino. Simply use the male to female jumper leads to connect the two together as described below and in fig.1:

HCSR04                                      Arduino

VCC-----------------------------------------5V

Trig------------------------------------------D3

Echo----------------------------------------D2

GND---------------------------------------GND

 

Step 2

Solder the KY1602 module onto the 1602 LCD screen. Pin 1 on the KY1602 module is the one closest to the 4 data and power pins. Once soldered, you can now connect the LCD display to the Arduino as shown in fig. 1.


                                                                               fig. 1

 

Step 3

Connect the Arduino to a computer and install the libraries mentioned above. If you need help installing the libraries, CLICK HERE for a quick tutorial.

 

Step 4
You can now start writing the code to get this all working:

First, clear the IDE window. Then, include the aforementioned libraries:
 

   
#include <HCSR04.h>
#include <LCD_I2C.h>
   

Initialize the HCSR04 sensor. The numbers in the brackets correspond to the trigger and echo pins respectively:

   
HCSR04 hc(3, 2);
   

Initialize the KY1602 I2C LCD driver (address 0x27 in this example) and specify the LCD display (in this case 16 characters, 2 rows):

LCD_I2C lcd(0x27, 16, 2);
   

Begin the void setup function. Initialize the LCD screen and turn on the backlight:

   
void setup()
{
  lcd.begin();
  lcd.backlight();
}  

Begin the void loop function. Set the cursor to the first character:

void loop()
{
    lcd.setCursor(0,0);

Print the distance calculated by the sensor on the LCD screen:

    lcd.print(hc.dist());
   

Add 100ms delay:

delay(100);                
}
   

The completed code should look like this:

#include <HCSR04.h>
#include <LCD_I2C.h>

HCSR04 hc(3, 2);
LCD_I2C lcd(0x27, 16, 2);

void setup()
{
  lcd.begin();
  lcd.backlight();
}

void loop()
{
    lcd.setCursor(0,0);
    lcd.print(hc.dist());
    delay(100);                
}
