Don't expect them all to work, but seller will quickly send replacements
Cheap price, but also cheap quality. Don't expect all of the transmitters/receivers you initially receive to work. However, I contacted the seller about my my broken ones and they sent replacements within days. If you're willing to be patient and email the seller, then you'll be able to get all working pieces.

These units seem to work well. I’ve only used two transmitters and one receiver so far, but they’ve worked with an Arduino quite well (with a basic IR library).

Worked exactly how I needed them to. Some. Of the IR LED's are mounted a tad bit skewed but nothing a little push couldn't correct.

4.0 out of 5 stars Arduino integration requires extra steps
Reviewed in the United States on January 5, 2024
Verified Purchase
The receivers work flawlessly with an arduino uno, and I was able to record IR commands from a remote in a matter of minutes.

The Transmitters were a different story. If you are trying to use them with an arduino, you will need to provide more power than the digital pins can provide. I put a transistor in front of them, and they are working well now, with the caveat that they only have about 4 ft of range in my current setup. I haven't spent time trying to increase the range further.

As an aside, the transmitter has three pins, but the VCC isn't actually connected to anything as far as I can tell.

5.0 out of 5 stars Works just fine with 3.3v ESP8266
Reviewed in the United States on March 12, 2020
Verified Purchase
Both the receiver and transmitter worked fine with my 3.3v ESP8266 NodeMCU board.
I just connect the VCC, GND, DATA pins directly to ESP's 3.3v, GND, D5 (in my case) pins.
Used the IRRemoteESP8266 library.
The transmitter isn't terribly wide (Can't bounce off the ceiling like my remote can) but range of at least 5-10 ft... haven't tried farther.

3.0 out of 5 stars emitters just don't work; receivers work fine
Reviewed in the United States on December 26, 2021
Verified Purchase
I got 3 receiver modules and 3 emitter modules. I see no indication that the IR LEDs are emitting through my phone's camera. I tried the visible LED trick to check wiring, and even a visible LED is not driven by the board. it looks like the board's internal circuitry is incorrect and just does not fire the LEDs at all. (I do see the status indicator LED, though, so the board is receiving a signal.) Not only that, but attempting to direct drive the IR LEDs does nothing, so they are either all dead or require a lot more current than expected.

In retrospect, I should have just bought a bag of IR LEDs and used resistors.

The _receiver_ boards work flawlessly, though.

4.0 out of 5 stars Works okay
Reviewed in the United States on October 23, 2020

Modules are for 38KHz IR remotes. The transmitters are standard IR emitting LED's - there is no internal/external oscillator on the transmitters. The other interesting thing about the transmitters are the 3 pins: VCC, GND, SIG but in reality only 2 pins are necessary. There is a red LED on the transmitter for a visual indication.
The receivers are also 3 pin: VCC, GND, SIG - the SIG output is active low. Again, a red LED is available for visual indication.
These are primarily used for IR Remote Control, but I used them to develop an Arduino Morse Code transceiver (in place of radio equipment). The Morse Code 'pulses' are much wider than normal IR clock pulses.
The IR receiver device contains an integrated circuit built internal to it that filters & decodes the clock envelope. It also contains an Automatic Gain Control (AGC) circuit that gets 'saturated' if the clock envelope is too long.

The workaround is to use one of the Arduino timers to generate a 38KHz, 50% duty cycle squarewave & interrupt on one digital pin. An interrupt service routine counts the number of interrupts and 'gates' the squarewave on for 8 counts and off for 8 counts and outputs it to another digital pin. This pin feeds the (-) side of the IR emitter. The Morse Code digital output pin feeds the (+) side of the IR emitter.

I bought a pack of Gikfun 38khz Ir Receiver Ir Transmitter Sensor Module Kit from Amazon.
The receivers are working fine. However, all of the three transmitters are faulty and even the indicator LED on them is not blinking.
I tried changing the ambient light conditions, reducing distance but none of the approaches have worked so.
