IR Transmitter and Receiver Kit

Introduction

IR Transmitter

IR trnsmitter module can emit modulated 38KHz signal via Arduino programming to achieve simulate common remote control.

IR Receiver

IR Receiver Module is an Arduino compatible 38Khz IR detector which can detect modulated 38Khz around IR signal. Though programming Arduino ,IR receiver can achieve the fuction of decoding the remote control signal.

Specification

• Power Supply:5V
• Interface:Digital
• Modulate Frequency:38Khz

Applications

• Remote control
• TV control
• Air conditioning control

Example code

Transmitter

#include <IRremote.h>
IRsend irsend;
void setup()
{
 Serial.begin(9600);
}
void loop() {
   for (int i = 0; i < 50; i++) {
     irsend.sendSony(0xa90, 12); // Sony TV power code
     delay(40);
   }
 }

Receiver

#include <IRremote.h>
int RECV_PIN = 11; //define input pin on Arduino
IRrecv irrecv(RECV_PIN);
decode_results results;
void setup()
{
 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
 }
}

Note

Led on the IR transmmiter module should be directed at IR detetor on the receiving board for better result.
