Thank you ericgibbs.
I used IR LED as sender, TSOP as receiver same as the picture above.

 

Hi L,
To get you started, use a simple IR receiver module, then load the IR Codes sketch I posted in an Arduino.
Then point one of your Remote transmitter modules at the IR receiver diode, about 3 ft away, press a remote button and the Arduino IDE serial monitor should print the Code Type it is using.

Tables for the Coding type are available on YouTube.

Using a TSOP as an RX detector may be a problem, it will require some testing.
You could try it with the above Sketch, post what you get.
I may have a TSOP 'somewhere' in stock.

Update:
Have you seen this,
https://www.instructables.com/Infrared-Remote-and-IR-Receiver-TSOP1738-With-Ardu/

 

hi Laodam.
I have one of these keypad remote control units, ref video and a couple of TSOP1838's.
So if you have a Sketch, we can compare results with TSOP's

Updated:
Fully tested with a TSOP1838, Arduino UNO and a number of Remote Controls, OK.

I did quite few of remoter test a month ago, all of them received good results by TSOP1838. I will go find the code I used to compare yours above.

Now my question is how to use a IR LED instead of a remoter as a sender to send signal.

 

hi L.
Do you have the receiver Sketch working with any remote sender.?

Thank you ericgibbs.
Yes, I did few of that work well with remoters.
One of it is the Arduino Example 'SimpleReceiver' from 'IRremote' library.
The same sketch doesn't receive my IR LED sender at all.
I also tested the Example 'SimpleSender' from the same library. but the receiver result seems not what I need?

SimpleReceiver serial monitor of NEC remoter:


SimpleReceiver for SimpleSender:


BTW.
This sending code works well, got receiver:
Protocol=NEC Address=0x102 Command=0x34 Repeat gap=47500us

void loop() {

  if (digitalRead(button) == HIGH) {
    // Results for the first loop to: Protocol=NEC Address=0x102 Command=0x34 Raw-Data=0xCB340102 (32 bits)

    uint16_t sAddress = 0x0102;
    uint8_t sCommand = 0x34;
    uint8_t sRepeats = 1;

    IrSender.sendNEC(sAddress, sCommand, sRepeats);
    /////   IrSender.sendSony(0x0, 0);  ///// WAS:  irsend.sendSony(0x0, 0);
    delay(2000);
  }
}

This code doesn't receiver that results, why?

void loop() {

  if (digitalRead(button) == HIGH) {
    // Results for the first loop to: Protocol=NEC Address=0x102 Command=0x34 Raw-Data=0xCB340102 (32 bits)

    uint16_t sAddress = 0x0102;
    uint8_t sCommand = 0x34;
    uint8_t sRepeats = 1;

    IrSender.sendNEC(sAddress, sCommand, sRepeats);
    /////   IrSender.sendSony(0x0, 0);  ///// WAS:  irsend.sendSony(0x0, 0);
    delay(2000);

    sAddress = 0x80;
     sCommand = 0x45;
     sRepeats = 1;

    IrSender.sendNEC(sAddress, sCommand, sRepeats);
    delay(1000);
    
  }
}

 

I have tested few of IR LED or modules, seems all of them working at very short distance, mostly from few cm up to 1 meter. are there any long distance ir transmitter, say 5 meters? OR how can increase its transmitter distance?
Thanks
Adam

 

hi L,
Do you have model numbers our type for the IR emitters you have tried, as you may know they have different beam width for some models?

You can use small low cost lenses that will pass IR that will focus the IR beam.

Thank you ericgibbs.
What I have in hand are as picture, I'll check the link you posted.
Also, how to aim the IR Senders/Transmitters each other if apart from 2 meters?
Are there exist hemispherica LED that can emmitter like a scalloped seam not just a cone?

 

Hi Adam,
With IR LED's having a Vfwd of about 1.2V you can have two in series from 3v, doubling the IR light output.
Many home TV remotes have two emitters.

Are you aware of the beam angle of an LED? As you can from the first diagram of a particular LED that there is a reduction in intensity directly in front of the LED which may seem counterintuitive. The second diagram has a "narrow beam angle".

I'll test it out.
I got a little confused of:

1. used IR LED as sender and IR photoresistor as receiver, seems can only receive an analog signal?
my test shown a reading varies with distance, but a short distance say 0.5M, how to increase it?

2. used IR LED or module as sender and IR module like TSOP1838 as receiver can decode and receive different code, right?
my test shown this type can transmission upto 5meters. But seems can't get reading varies with distance?

Thank you k1ng 1337.
Actually what I expected is a emitter area of a sector of 0-180 degree like your first picture all. seems can only get it by mount many LEDs fan-shaped？

 

hi Adam,

Yes I would expect that when using a simple IR receiver.

2. used IR LED or module as sender and IR module like TSOP1838 as receiver can decode and receive different code, right?

Yes, you can use that sketch I posted to see the codes on the IDE serial monitor.

my test shown this type can transmission upto 5meters. But seems can't get reading varies with distance

I would say 5mtrs is a good range, what part of the reading varies with distance.?

1. The second type's 5 mtrs is good, can it also show reading varies with distance in any way like the first type's ?

2. the first type analog value reading varies with distance is what I think I need now, but too short distance.

I searched online that the pictures below, one got max 30cm and other one got 500cm range. I am not use that sensor, I use just half of that, say emitter or receiver. but how the 'GP2Y0A710K0F' got 500cm? does it used different IR LED or just some kind drive circuit?

 

Hi Adam,
Could you post a short specification of the project so that I understand what you are trying to achieve.?

thanks.

 

hi Adam,
He has 9, IR emitters on that panel.!
You will get a longer range with that level of IR at 200Hz.

I don't understand your question from the syntax you are using. I recommend you take more time to write out your thoughts as this will help people help you!

What I mean is can a IR LED emitter a semicircle beam, like the #31's first picture from 0 - 180.
