Instructions lacking
Hardware is fine and works as expected, but the included documentation was sparse. Had to search online for wiring diagrams.

Great for competitions
Used this for a university robotics contest. Very reliable tracking even on slightly worn tape lines. Highly recommend for students.

Bulk order success
Bought 10 units for our workshop. All units tested and working perfectly. Consistent quality across the batch.

Good sensitivity
Detects lines well but needs careful mounting height adjustment. Once set up correctly, it performs reliably. Good value for the price.

Perfect for Arduino Bot
Works flawlessly with my Arduino Uno project. Calibration was easy using the onboard potentiometers. The 7 channels provide smooth line tracking.
Q: Can I use this sensor outdoors?
A: Not recommended. Direct sunlight contains infrared light which can interfere with the sensor readings.
Q: What is the maximum speed it can track?
A: Tracking speed depends on your microcontroller processing speed, but typically it handles robots moving up to 1-2 meters per second.
Q: Does it work on white lines on a black floor?
A: Yes, the hardware detects contrast. You simply need to invert the logic in your code to handle white lines on black.
Q: Is this compatible with Raspberry Pi GPIO?
A: Yes, it works with 3.3V logic systems like Raspberry Pi. Ensure you connect the VCC to 3.3V pin.
Q: What type of jumper wires fit the headers?
A: Standard 2.54mm pitch female-to-female or female-to-male jumper wires fit perfectly on the pin headers.
