โมดูลรับอินฟาเรด HX1838 Infrared Receiver Module KY-022

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.

Links to the required libraries for KY-022 Arduino example sketch can be found in the Downloads section below.

#include 

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
}
