Perfect for my sumo bot
Calibration was incredibly easy with the one-touch button. The 8-channel precision helps my robot stay on track even during sharp turns.

Great for STEM classes
Bought 10 for our robotics club. Students find the auto-calibration feature very intuitive. Durable construction too.

Best line follower I've used
The 8-channel precision is noticeable compared to cheaper 3-channel modules. Auto-calibration saves a lot of time during setup.

Good sensor, tricky wiring
Works well once connected properly. I had to double-check the pinout for my specific board, but the performance is solid.

Sensitive to light
Works indoors perfectly. Just be aware that strong direct sunlight can interfere with the infrared sensors outdoors.
Q: Does this work with 3.3V logic boards?
A: Yes, the module supports operating voltages between 3.3V and 5V DC, making it compatible with most 3.3V logic microcontrollers.
Q: Do I need to solder headers before use?
A: Headers are typically pre-soldered on this module. You can connect directly using jumper wires without additional soldering.
Q: Can it detect a white line on a black surface?
A: This module is optimized for detecting black lines on a white background. Inverted detection may require additional code logic and is not guaranteed.
Q: What is the sampling rate of the sensors?
A: The digital output responds instantly to line changes. The actual sampling rate depends on your microcontroller's code loop speed.
Q: Is the connection cable included in the package?
A: Yes, a standard Dupont cable is included to connect the sensor module to your main controller board.
