Perfect for my Arduino robot car

This 8-channel sensor works flawlessly with my custom-built robot. The line tracking is very smooth, and the obstacle avoidance feature adds an extra layer of safety. Setup was straightforward.

Responsive and reliable

The response time is incredibly fast. I used it for a high-speed line follower, and it handled sharp turns without losing the track. Highly recommended for intermediate makers.

Good but requires calibration

Works well once you spend time calibrating the potentiometers for your specific environment. Don't expect it to work perfectly out of the box without adjustment.

Best sensor module I've used

I have tried several line trackers, and this 8-channel version offers the best precision. The ability to detect obstacles simultaneously is a huge plus for autonomous navigation.

Great value for the price

Bought this for my son's science project. It detects lines accurately on white paper with black tape. The only minor issue is that the sensitivity needs fine-tuning under bright lights.

5 FAQ

Q: Is this module compatible with Raspberry Pi?

A: Yes, since it outputs digital TTL signals, it is fully compatible with Raspberry Pi GPIO pins as long as you connect the VCC to 3.3V or 5V appropriately.

Q: What is the effective detection range for obstacles?

A: The obstacle detection range is typically between 2cm and 15cm, depending on the reflectivity of the object and ambient light conditions.

Q: Can I use this outdoors?

A: While it can work outdoors, direct sunlight may interfere with the infrared sensors. We recommend using a shield or testing in shaded areas for best results.

Q: How do I adjust the sensitivity?

A: There are small blue potentiometers on the board. Use a small screwdriver to rotate them clockwise to increase sensitivity or counter-clockwise to decrease it while testing on your line.

Q: Does the package include connecting wires?

A: The module usually comes with header pins installed, but connecting jumper wires are sold separately unless specified in the bundle option.
