Decent but fragile
The pins bent easily during shipping. Sensor works though after straightening them.

Good value
Works well but needs careful calibration of the potentiometer to avoid false positives.

Perfect for Robotics Club
Used this for our high school robotics competition. The line detection is very stable and consistent.
Q: What is the detection height?
A: Optimal distance is 5mm to 10mm from the surface.
Q: Does this work with 3.3V logic?
A: Yes, it operates between 3.3V and 5V DC.
Q: How many wires needed?
A: Typically 6 wires per module for full channel access.
Q: Can I use this on carpet?
A: It is designed for smooth surfaces like tape on wood or tile.
Q: Is code included?
A: No, but sample Arduino code is available on our wiki.
