KY-022 Infrared Receiver Module

This module consists of an 1838 IR receiver, a 1kΩ resistor, and a LED. It works together with the KY-005 IR transmitter module. Compatible with popular electronic platforms like Arduino, Raspberry Pi, and ESP8266.

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.

The following Arduino sketch uses the IRremote library to receive and process infra-red signals. Use the KY-005 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
}
