Perfect for my Arduino Robot
This sensor module works flawlessly with my Arduino Uno project. The 8 channels provide smooth line tracking without jerky movements. Calibration was straightforward using the onboard potentiometers.

Good sensitivity
Works well but requires some tuning depending on ambient light. Once calibrated, it follows the line accurately. Good value for the price.

Decent but tricky
The sensor works, but the instructions could be better. I had to watch a tutorial to understand how to adjust the sensitivity properly for my specific track surface.

Fast line tracking
My robot car moves much faster now compared to using a 3-channel sensor. The extra channels help anticipate turns better. Fast shipping too!

Excellent build quality
The PCB is sturdy and the components are soldered well. I appreciate the clear labeling for each channel pin. Highly recommended for robotics hobbyists.
Q: Are jumper wires included in the package?
A: No, the package includes only the sensor module. Jumper wires need to be purchased separately.
Q: Can I use this sensor outdoors?
A: Outdoor use is not recommended as direct sunlight contains infrared light which may interfere with the sensor's accuracy.
Q: Is this compatible with 3.3V microcontrollers like ESP32?
A: Yes, the operating voltage range is 3.3V to 5V DC, so it is fully compatible with ESP32 and similar boards.
Q: Does it work on a black line with a white surface?
A: Yes, it is designed primarily for detecting black lines on a white surface, but sensitivity can be adjusted for reverse scenarios.
Q: Does this come with a library for Arduino?
A: No specific library is required. It outputs digital signals that can be read using standard digitalRead functions in Arduino IDE.
