Revainrating 4 out of 5

The output goes LOW when activated.

Missing documentation results in BOTH pins Hi (wrong) and Pin Lo (right) when activated. Limited spacing adjustment (1/2" to 3"), but that's fine for my application.

Pros
  • Computers and Accessories
Cons
  • I will add later

Range not as advertised

This sensor has a terrible range. All 10 sensors in a pack have a maximum range of 7cm or less. There are no 30 cm declared. I cannot recommend this sensor.

Pros
  • Single board computer
Cons
  • Big and bulky

The output goes LOW when activated.

Lack of documentation results in BOTH Hi (wrong) and Lo (true) contacts when activated. Limited spacing adjustment (1/2" to 3"), but that's fine for my application.

Pros
  • GOLS certified
Cons
  • Only available in black

Wonky Sensor

No idea why but they seem pretty cheap. Like sometimes gives me funny reviews for no reason. It's like having to manually bend some pins and play with the potentiometer to get it reading correctly. Some of them were fine, some weren't. It seems like they weren't made with precision, to be honest.

Pros
  • Dope 🔥
Cons
  • Expensive

Not as good as other types of IR modules sold at Revain

There are two problems with these modules: 1. They only have a 100 ohm resistor between Vcc and the LED. This is way too low and explains why a lot of people complain about LEDs burning out with continuous use at 5V. I'm pretty sure this is normal at 3.3V.2. The transmitter and receiver are in close proximity to each other and there is no "protection" between them. Thus, the receiver tends to register false positive readings. If you put a sheet of paper or plastic in between I'm sure it will…

Pros
  • Great for a small home
Cons
  • Questionable purchase for the elderly
