38 Khz IR Detector

These very nice 38khz IR detector are often used for TV remote control, but we know better, right? These sensors are often hacked into a object detectors when teamed up with a suitable IR LED, providing a reflective range of up to 3 feet.

These sensors provide a very clean signal and won't even saturate in sunlight. Definitely an improvement over the old "Sharp tin-can" sensors!
