As expected

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.

Pros
  • Withstanding voltage: 250 VAC (50/60 Hz for 1 minute); Electrical Life: 100,000 cycles
Cons
  • boring packaging

Inaccurate and poor sensor placement

This sensor is unreliable and may give false alarms 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.

Pros
  • Kit contains: 3 modules per pack
Cons
  • Cable shorter than other sensors

Unreliable IR receiver

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.

Pros
  • KY-004 3 pin push button switch sensor module
Cons
  • Some errors
