I’m using QTR-1RCs for an outdoor line sensing robot. The surface is uneven and the narrow operating range is causing me problems. I think I need sensitivity about .5"-1" away. Can I increase the range of the sensors by adding an infrared LED? What about putting two QTR-1RCs next to each other so the IR beams overlap?
Am I using the wrong sensor all together?
I’m looking for a simple solution; my background is in software and I currently know very little about electronics.
