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
}
}
