Infrarood reflecterende afstandssensor

The potentiometer made it easy to dial in the exact sensing distance I needed, and the digital output is nice and crisp. It picks up a matchbox from about 12 inches away perfectly for my project.

The digital output flips on and off with rock-solid reliability when I move my hand closer or farther, and the range adjustment knob is surprisingly easy to dial in for my bench setup. Took me about two minutes to get the sensitivity where I needed it.

The on-board potentiometer made tuning the detection distance way easier than I expected, even for my shaky hands. Plugged it into my project and it's been rock-solid at sensing objects within a few centimeters, no false triggers. Exactly what I needed for a reflective sensing setup.
