  • Ultrasonic Ranging Module for Arduino

    Ultrasonic Ranging Module for Arduino

    Ultrasonic ranging module for Arduino and other microcontroller projects

     
    This is a module with a 40kHz ultrasonic transmitter / receiver pair mounted on the front of a small PCB, with the required control circuitry on the back.
    It sends a short 40kHz square wave out, and calculates the distance by recording the time it takes the wave to return to the sensor.
     
    Voltage : 5VDC
    Working Range : 20mm to 4500mm
    Accuracy : 2mm


    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
    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);                
    }
    
       
    

     

     
    Step 5
    Press the “Upload” button at the top (button with tick, located below “File”). The IDE will now compile the code and upload it to your Arduino (this will take a few moments).
     
    Step 6
    All done! The LCD will now start to display the distance calculated by the sensor.

  • PIR Sensor Module for Arduino

    PIR Sensor Module for Arduino

    PIR sensor module for Arduino and other microcontroller projects

     
    The HCSR501 is a PIR (Passive Infra-Red) sensor that can detect the presence of people by measuring the infrared radiation radiated by the body. It can be used in a vast and diverse number of projects, including but not limited to: automated lighting systems, burglar alarms, automated door systems, etc.

    Principle of operation
    All objects with a temperature above absolute zero (0 kelvin) emit electromagnetic radiation. The higher the temperature of the object, the smaller the wavelength of the radiation emitted. The normal human body temperature is 37°C (310.2 kelvin) and it therefore emitts infrared radiation (mostly at a wavelength of 12µm). The PIR sensor can sense when a person has walked into its field of view by measuring the difference in the infrared radiation received from the ambient environment and the human body. 
     
    Voltage : 5-20VDC
    Power Consumption: 64mA
    Logic output: 3.3V
    Range: 7 metres, (<120°)
    Lock Time: 200 miliseconds
    Operating temperature range: between -15°C and 70°C
