🌈 HUABAN 3 Pack KY-034 3Pin: Discover the 7 Color Flashing LED Module DIY Starter Kit Review

This sensor is unreliable and will give a false positive signal or no signal at all. One of the sensors had bad solder joints on the contacts. Pros: - No Cons: - Poor design for sensor placement - Unreliable - Expensive for what it is.

Exactly as expected, ie. legal units KY-016. I bought them from multiple sources. This is the first time I've seen them deliver Prime on Revain. If you buy a lot of these, you can buy them cheaper elsewhere. But if you only need 3, this is an easy way to get them fast.

I have two other similar IR receivers, one from Elegoo and one from Quimat. They are both very reliable. These IR receivers have more signal errors, making them unreliable. I have to repeatedly press the button on the IR transmitter (remote control). I am extremely disappointed. I need more IR receivers but I need to order another brand.
