IR Infrared Receiver Sensor Module KY-022

The KY-022 IR Infrared Receiver Sensor Module is a versatile component designed for decoding signals from most IR remote controls. It uses the reliable VS1838B IR receiver chip, tuned to detect 38kHz modulated infrared signals. These signals allow remote commands to be encoded with different protocols, preventing interference when multiple devices operate nearby. The module can also act as a simple IR locator, detecting object movement between the IR LED and the receiver, making it useful for robotics and automation projects.

How to Work With KY-022

The KY-022 receives infrared signals from most remote controls. Using the IRremote Arduino library, it can decode the signals and allow you to trigger actions like turning on LEDs, controlling motors, or operating robots. Make sure the IR remote and sensor are within ±45° for reliable detection.

Arduino Libraries

  • IRremote: Install via Arduino IDE Library Manager (Search: IRremote)

Arduino Example Code

#include <IRremote.h>

const int RECV_PIN = 2;  // KY-022 signal pin
IRrecv irrecv(RECV_PIN);
decode_results results;

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

void loop() {
  if (irrecv.decode(&results)) {
    Serial.print("Received IR code: ");
    Serial.println(results.value, HEX);  // Print the received code in HEX
    irrecv.resume(); // Receive the next value
  }
}
