Excellent sensitivity adjustment

The potentiometer allows for fine-tuning based on ambient light conditions. Works flawlessly on black tape against a white background. Highly recommended for competitive sumo or racing bots.

Works well but needs careful mounting

The sensor works as advertised, but you need to mount it at the precise height specified in the manual for optimal performance. A little trial and error was needed for my specific chassis.

Good value, clear documentation

As a beginner, I appreciated the clear pinout labels on the board. It took me a few tries to get the calibration right, but once set, the robot follows lines very accurately.

Great for classroom projects

Bought five of these for our high school robotics club. They are robust and easy to interface with Arduino. Only minor issue is the included cables are a bit short, but that's easily fixed.

Superior to generic alternatives

The build quality is noticeably better than cheaper unbranded versions. The IR sensors respond quickly to changes in the line, allowing for higher speed navigation without losing the path.

Perfect for complex line following

The 8-channel setup provides much smoother tracking than the standard 3 or 5 channel modules I've used before. The one-key calibration is a huge time saver when switching between different track tapes.

5 FAQ

Q: Can this module be used directly with a 5V Arduino Uno without a logic level converter?

A: Yes, the module operates on 3.3V to 5V and outputs TTL levels compatible with 5V microcontrollers like the Arduino Uno.

Q: Does this support analog output or only digital?

A: This specific model provides digital output signals for each of the 8 channels. If you require analog readings, please check our analog sensor series.

Q: How do I perform the one-key auto calibration?

A: Place the robot on a solid black surface, press and hold the calibration button for 3 seconds until the LEDs flash, then release. It is now calibrated.

Q: Is the cable included in the package?

A: Yes, the package includes one 20cm Dupont wire cable set for easy connection to your microcontroller.

Q: What is the recommended distance between the sensor and the floor?

A: For best results, we recommend mounting the module approximately 10mm to 15mm above the tracking surface.
