Not much to say about these ones I purchased it to fix a couple of broken receivers and transmitters They work fine They arrived nicely back And very quickly for the money You could probably do better But I'm happy with my purchase and if you need something in a hurry I think it made sense to get these again

Something of note is that the sensor (black component) seems very slightly taller/longer than the LED. I've set the sensor with a 5.1kΩ or 2.25kΩ pulldown on the 'long leg' and direct to power on the "short leg" and you can get a reading as the voltage level goes low on the 'long leg'. I am still learning about these which are apparently photodiodes, and have not seen much literature on how to use these. But I can say the 'long leg' output will rise to high voltage when exposed to PWM at the appropriate light wavelength/frequency.

It worked on my cheap cronograph

The product worked as advertised, but the supplier was slow to respond (haven't responded yet) and they have no documentation on the proper wiring for these.Eventually, I found the info I needed elsewhere, but was frustrating nonetheless.For anyone who's equally frustrated, see the attached image for a rough wiring diagram that I found to work

Although they didn't work for the intended project, (no fault on the product). They will come in handy for future projects. I gave 5 stars because the customer service at HiLetgo was outstanding. Answered email next morning. Answered every question, I will continue to use this company for all my led needs.

took two tries, thees have a lower voltage drop so use a 180 resistor in series with the emitter or it will only last for about a week.

Good price, I have not tested them yet. Takes time to come.
