Compact and easy to integrate
Love the compact size of this Huaner module. It fit perfectly on my custom chassis. The pinout is standard, making wiring incredibly simple. The LEDs clearly show the status of each channel.

Great starter sensor
As someone new to robotics, this was easy to understand and connect. The documentation could be slightly better, but there are plenty of tutorials online for this type of sensor. Works as advertised.

Excellent for school projects
Bought this for a university robotics competition. The four-way recognition helps the car make smooth turns rather than just stopping. Very reliable performance throughout the event.

Works well in normal light
The sensor performs great indoors under artificial light. However, I noticed some interference when testing it near a window with direct sunlight. You need to shield it or adjust sensitivity carefully for outdoor use.

Perfect for my line follower robot
This 4-channel sensor works flawlessly with my Arduino project. The sensitivity adjustment is very precise, allowing it to track black tape on white surfaces without any issues. Highly recommended for beginners.

Good value but needs calibration
The module is solid and well-built. It took a little time to calibrate the potentiometers for my specific lighting conditions, but once set, it tracks lines smoothly. Great price for a 4-way sensor.
Q: Does the package include mounting screws?
A: The package includes the sensor module and header pins. Mounting screws are not included, but the board has standard 3mm holes for easy integration with most chassis kits.
Q: How do I adjust the sensitivity if the car keeps drifting off the line?
A: Use a small screwdriver to turn the blue potentiometer on the module. Turn it slowly while observing the indicator LED until it switches state exactly when crossing the line edge.
Q: Is this compatible with 3.3V microcontrollers like ESP32?
A: Absolutely. The module operates within a 3.3V to 5V range, making it fully compatible with ESP32, ESP8266, and standard 5V Arduino boards.
Q: What is the maximum detection distance for obstacles?
A: When used for obstacle avoidance, the effective detection range is typically between 1cm and 2.5cm, depending on the reflectivity of the object and ambient light.
Q: Can this sensor detect white lines on a black surface?
A: Yes, by adjusting the potentiometer, you can invert the logic to detect white lines on a dark background, though it is primarily optimized for black lines on white surfaces.
