IR receiver module reacts to 38 kHz modulated infrared light.
This module consists of a 38 kHz IR receiver, a 1kΩ resistor and an LED. It
works together with a 38 kHz IR transmitter or any regular IR remote
control. It’s compatible with popular electronic platforms like
Arduino, Raspberry Pi and ESP8266.
Pinout and Connection to Arduino
Connect the Power line (middle) and ground (-) to +5 and GND respectively. Connect signal (S) to pin
11 on the Arduino. Line un IR receiver and transmitter.

Arduino Example Sketch
The following Arduino sketch uses the IRremote library to receive and process infra-red signals. Use
the IR transmitter module to serially send data to this module.
#include <IRremote.h>
int RECV_PIN = 11; // define input pin on Arduino
IRrecv irrecv(RECV_PIN);
decode_results results; // decode_results class is defined in IRremote.h
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
}
delay (100); // small delay to prevent reading errors
}
