The sensor has great build quality and works well. It has a green LED, it turns on when an object is within its detection range. The detection range is less than 15 cm. The output is high if no object detected, it turns low when an object in in range. The range can be adjusted using the pot, but it is very limited. I was hoping to get proportional signal from this sensor's output terminal (voltage is proportional to the distance), unfortunately it does not do that, it just gives you a signal whether there is an object in front of the sensor.

PROS
works right out the box works at both 5v and 3.3v
CONS
it will be nice to have pins not soldered on
Works well just like official ones. When connected to USB or powered by 5v on the 5v pin, it is a 5v device. When powered by Vin pin, it becomes a 3.3v device - 5v pin now output 3.3v. The device works perfectly fine in this mode. So you get both versions in one device, just hook it up the way you need.
