Good Quality. Range is Okay.

Good Quality. Range is Okay.
I used them to build an IR learner and transmitter with Arduino Nano, and they worked great. Total success. The transmitter range is okay.

I used these IR LED and receiver pairs to build a true learning universal remote control using a Raspberry Pi Zero W. The unit can be programmed from any remote that uses the same frequency of IR as these by pointing the remote at the receiver and capturing each button. It can then control the device the original remote was for using the LED. The whole thing is controlled from a web browser on my phone or tablet. They work wonderfully.

5.0 out of 5 stars Worked with Raspberry Pi 3

I needed an IR receiver to connect to the Raspberry Pi3 since I use it as a media player. I wanted it to work with an IR remote to power On/Off the Pi, and to be able to use the Pi to control the media program with a Logitech universal remote.

While I only used 1 IR receiver module out of this kit, I have spare parts for future products.

Installation was pretty easy. There are lots of online resources which will tell you how to connect the IR receiver to your Pi and how to program it for your particular use.

The receiver worked well, and I would order this again.

4.0 out of 5 stars Arrived quickly, works well after some trials
Reviewed in the United States on October 25, 2014

These arrived much sooner than promised and work well. It took a little searching to figure out how to use them for my application, which was a simple blocked beam detector using an Arduino board.

In case anyone has a similar application, I found I needed a 100 Ohm resistor in series with the diode to get sufficient output.

The emitter was harder to figure out. With the emitter facing toward you, the pin on the right goes to +5V, the center pin goes to ground, and the left pin goes to the digital input.

5.0 out of 5 stars Great Product! You'll need a good IR library to make it work well. Used these successfully in a couple of my projects.

This is an excellent product. I have used them in a couple of Home automation projects you can see in action here:

The IR Receiver/Transmitter Project:[...]
This project is a test bed that I set up to test both, the IR Receiver and Transmitter.

The Home Automation Project:[...]

This is a more practical home automation set up that makes use of the IR Transmitter product. I have been testing this system for more than 2 months to control my home entertainment system, and the IR Transmitter has been working reliably without any issues.

Overall, an inexpensive but reliable and durable product to keep your project up and running!

5.0 out of 5 stars Receiver works like a charm
Reviewed in the United States on February 11, 2014

I was a bit concerned before buying this as previous reviewer could not make it work. However, this is possibly the cheapest receiver/ transmitter combo available in Amazon, so just took the risk of buying it. Ships from China, and takes some time to arrive but does work very easily. I have not yet used this in any project, but tried out the sample from learn<dot>adafruit<dot>com<slash>ir-sensor<slash>using-an-ir-sensor and receiver works like a charm printing out IR code sequence. I will try to send back the IR code sequence using the transmitter and see how it works. Hope this helps someone.

3.0 out of 5 stars My Honest Review
Reviewed in the United States on October 12, 2017

3 of the IR LED emitters were duds, but, all the receivers worked.

I tested the IR LED lights on a DSLR camera that doesn't have an IR filter. I used a 555 timer with a 5v power supply to attain a 38kHz frequency on the LED. The LEDs have low luminosity, thus, these LEDs won't for my application but may work for short distance remote control applications.

Receivers were digital based, a digital (0 or 1) output occurs when the receiver detects the 38kHz LED. The receiver won't detect the LED if the frequency isn't at 38kHz... plus or minus some amount which I haven't tested. The output doesn't last longer than a few seconds, even when the receiver points directly at a correct LEDs for longer periods of time. This means the receiver is not continuous, and will never be able to relay a positive output for longer than a few seconds at a time. If you're looking for a receiver that will continuously give an accurate output depending on if the receiver detects the LED, look for another component.

Great price/value. The IR recievers work great. I tested with arduino and IRLib (ir-decode example)
The IR LEDS are fairly bright with 100 ohms, but try higher and come down...
I didn't try to measure the distance or angle for the IR LEDs, but the receivers have the usual long range seen by your TV and other IR devices

Works great, I've connected both a transmitter and a receiver to my Raspberry pi and now I control all the IR devices in my home, I've used a 100 ohm resistor as some people suggested and it's working fine, I've not experimented with different resistors and I don't know how that will affect the range
