Great for competition bots
Used this for a university robotics contest. The 4-channel setup allows for smooth line following algorithms.

Good sensitivity
The detection range is decent. Had to adjust the height from the ground slightly to get optimal readings. Good value.

Robust and reliable
Been using it for weeks on my smart car kit. No false positives so far. The LEDs help visualize detection status.

Instructions unclear
The module works well but the wiring diagram provided was a bit vague. Had to look up online tutorials. Product itself is fine.
Q: What is the detection distance?
A: Typically 1mm to 25mm depending on surface reflectivity.
Q: Can I use this outdoors?
A: It is designed for indoor use; strong sunlight may interfere with IR sensors.
Q: Is this compatible with Raspberry Pi?
A: Yes, it works with Raspberry Pi GPIO pins using 3.3V logic.
Q: Does it work on white lines with black background?
A: Yes, but you may need to invert the logic in your code.
Q: Are jumper wires included?
A: No, jumper wires are sold separately.
