Solid performer

Works as advertised. The only minor issue is that the mounting holes are a bit close to the edge, but standard standoffs still fit. Good detection range.

Excellent response time

I was worried about latency, but the digital output switches instantly. The five channels provide great resolution for detecting curves and intersections in my robot course.

Perfect for my line follower bot

This 5-channel sensor works flawlessly with my Arduino project. The sensitivity adjustment is very precise, allowing me to tune it perfectly for black tape on a white floor. Highly recommended for beginners.

Great for university projects

Bought this for a final year project. It integrates easily with Raspberry Pi GPIO pins using a logic level converter. The status LEDs make debugging very easy.

Easy to use for beginners

I am new to electronics and this was very straightforward to connect. The documentation online is helpful, and the module itself is robust. No issues so far after a week of testing.

Good value, needs careful calibration

The module is well-built and the pins are clearly labeled. It took me a few minutes to get the potentiometer adjusted correctly for ambient light conditions, but once set, it tracks lines smoothly.

5 FAQ

Q: Can this sensor detect colored lines other than black?

A: The sensor detects contrast based on infrared reflection. It works best with black lines on a white surface. It may struggle with low-contrast colors or dark surfaces, as IR absorption varies by pigment.

Q: Does the package include connecting wires?

A: No, the package includes only the PCB module. You will need to solder your own header pins or connect wires directly to the pads. Jumper wires are sold separately.

Q: What is the maximum speed a robot can travel while using this sensor?

A: The maximum speed depends on your robot's control loop and motor response, but the sensor itself has a very fast response time. Most users successfully run line followers at speeds between 0.5m/s and 1.5m/s.

Q: How do I adjust the sensitivity if the LEDs are always on?

A: Use a small Phillips screwdriver to turn the blue potentiometer on the board. Rotate it slowly counter-clockwise to decrease sensitivity until the LED turns off when not over a line, then fine-tune for your specific surface.

Q: Is this compatible with 3.3V microcontrollers like the ESP32?

A: Yes, the module operates on a voltage range of 3.3V to 5V, making it directly compatible with ESP32, ESP8266, and 3.3V Arduino boards without needing a voltage regulator.
