ARDUINO / Infrared IR remote control 38kHz

Product description

ARDUINO / Infrared IR remote control 38kHz 

The cheapest way to remotely control a device within a visible range is via Infra-Red light. Almost all audio and video equipment can be controlled this way nowadays. Due to this widely spread use the required components are quite cheap, thus making it ideal for us hobbyists to use IR control for our own projects.

The new ultra-thin 38K universal infrared remote control, NEC encoding format 1-21-key remote control, USB port stereo, car MP3, foot bath, lighting, digital photo frame, microcontroller development board, learning board, etc.. 

Features: 
Remote control distance:                                     more than 8 meters
Launch tube infrared wavelength:                        940Nm
Crystal:                                                                 The oscillation frequency of 455 KHz
IR carrier frequency:                                             38KHz

Power supply:                                                      CR2025/160mAH
Button:                                                                  Free height is less than 3mm, the force 200-350g, the life of more than 200,000 time

 
Effective Angle:                                                     60°
Static Current:                                                       3~5uA, Dynamic Current: 3~5mA
Remote size:                                                         8.5 x 4 x 0.65cm(L x W x H)

Encoding: the encoding format of the NEC, upd6122 encoding scheme, the user code 00FF

Example code

#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
}
}
