Description:

the IR Infrared Wireless Remote Control Module Kit (HX1838 VS1838) typically operates at a frequency of 38 kHz and has a maximum operating distance of around 8 meters. It usually requires a voltage supply of 3-5V and consumes very little power, making it ideal for low-power applications. The module is commonly used in various electronics projects such as building a remote control car, controlling appliances in a smart home system, or designing a simple remote control.  It is important to note that the IR Infrared Wireless Remote Control Module Kit is not suitable for long-range or outdoor applications as its infrared signals can be easily obstructed by physical barriers. Additionally, the receiver module must be positioned in the line of sight with the transmitter for proper operation.

 

Principle of Work:

Infrared communication works by transmitting a modulated infrared light signal that carries digital information. The transmitter uses an infrared LED to emit the modulated light signal in a specific direction, and the receiver uses an infrared sensor to detect the signal. The modulated infrared signal contains two parts: a carrier wave and a data signal. The carrier wave is a high-frequency signal that is used to carry the data signal. The data signal is a low-frequency signal that represents the digital information that needs to be transmitted. When the receiver module receives the modulated infrared signal, it first filters out the carrier wave using a bandpass filter. It then demodulates the data signal using a demodulator circuit to extract the digital information. The demodulated data signal is then sent to a microcontroller for further processing.

In the case of the IR Infrared Wireless Remote Control Module Kit (HX1838 VS1838 compatible), the transmitter module sends out a modulated infrared signal when a button is pressed on the remote control. The receiver module detects the signal, demodulates it, and sends the information about the button that was pressed to a microcontroller. The microcontroller can then perform the desired action based on the information received.

Library:

To install the IRremote library, you can follow these steps:

1. Open the Arduino IDE
2. Go to "Sketch" > "Include Library" > "Manage Libraries"
3. In the "Library Manager" search bar, type "IRremote" and press enter
4. Select the "IRremote" library and click "Install"
5. Wait for the installation process to finish

If you encounter a problem with duplicated library, you can try these steps to fix it:

1. Close the Arduino IDE
2. Navigate to the Arduino libraries folder (usually located at "Documents/Arduino/libraries")
3. Find the "IRremote" library folder and delete it
4. Reopen the Arduino IDE
5. Follow the installation steps again to install the library

 

Code:  

This code uses an IR receiver and the IRremote library to receive signals from an infrared remote control. When a signal is received, the code decodes the signal to determine which button was pressed on the remote. If the button corresponds to turning on an LED, the LED is turned on. If the button corresponds to turning off the LED, the LED is turned off. 

 

#include "IRremote.h"

int RECV_PIN = 7;
IRrecv irrecv(RECV_PIN);
decode_results results;

int ledPin = 13;

void setup() {
  pinMode(ledPin, OUTPUT);
  Serial.begin(9600);
  irrecv.enableIRIn(); // Start the receiver
}

void loop() {
  if (irrecv.decode(&results)) {
    Serial.println(results.value, HEX);
    irrecv.resume(); // Receive the next value

    // Check the received button code
    switch (results.value) {
      case 0xFF6897:
        digitalWrite(ledPin, HIGH);
        break;
      case 0xFF9867:
        digitalWrite(ledPin, LOW);
        break;
    }
  }
}

First, the IRremote library is included at the top of the code. The variable RECV_PIN is set to 7 to specify the pin connected to the IR receiver module. The IRrecv object is then created to receive infrared signals on this pin, and the decode_results object is created to store the results of decoding the infrared signal. The LED is connected to pin 13, and pinMode() is used to set the pin as an output. Serial communication is also set up at a baud rate of 9600, which will be used to print the hexadecimal code of the button pressed on the remote control. In the loop() function, the irrecv.decode() function is used to check if an infrared signal has been received. If a signal has been received, the hexadecimal value of the button pressed is printed to the serial monitor using Serial.println(), and irrecv.resume() is used to receive the next signal. The code then checks the received button code using a switch statement. If the button code matches 0xFF6897, which is the code for the power button on many remote controls, the LED is turned on by calling digitalWrite(ledPin, HIGH). If the button code matches 0xFF9867, which is the code for the power off button on many remote controls, the LED is turned off by calling digitalWrite(ledPin, LOW).

• Carrier frequency: 38kHz
• Maximum reception distance: up to 18 meters
• Reception angle: +/-45 degrees
• Pinout: 3 pins (VCC, GND, OUT)
• Low power consumption

TSOP58438 Vishay:

• Operating voltage: 2.5V to 5.5V
• Carrier frequency: 38kHz
• Maximum reception distance: up to 45 meters
• Reception angle: +/-45 degrees
• Pinout: 3 pins (VCC, GND, OUT)
• Low power consumption
• Improved immunity against ambient light and electrical noise

The TSOP58438 Vishay has a longer maximum reception distance and improved immunity against ambient light and electrical noise, which can be important in some applications. However, the HX1838 is also a popular and reliable option with a lower operating voltage range and a lower cost. Ultimately, the choice between the two would depend on the specific needs of the application.
