Garbage value without pressing remote in Serial Monitor

Hi,
I m using TSOP 1738 ir receiver connected to Arduino then to my PC added Arduino-IRremote-master
library in Arduino(Version 1.6.7), I have uploaded below code to Arduino ,in serial monitor when I press remote button it is showing 80BF49B6 80BFC936 80BF33CC only when remote is pressed.

But in Laptop
Now I m using same TSOP 1738 ir receiver connected to Arduino then to my Laptop added Arduino-IRremote-master library in Arduino(Version 1.6.7), I have uploaded below code to Arduino ,in serial monitor it showing some garbage value without pressing remote.

Pls help me in this regard.

#include <IRremote.h>

int RECV_PIN = 11;

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
}
delay(100);
}

Regards,

How's it wired? Can you post a drawing (please, no fritzing)

Example of the "garbage" serial output?

My advice would be to stop the anonymous printing. If you preface everything that you print with some recognizable string, then you have a chance of defining where the "garbage" data is coming from.

The main problem behind garbage value is that you are using an outdated TSOP 1738.
i would recommend using TSOP 1838. I'm sure it will work.

Thank you for your contribution, but as the OP only posted once and that was in 2016 I doubt that he/she is around to heed your advice
