Perfect for my Arduino line follower
These sensors work flawlessly with my Arduino Uno project. The sensitivity adjustment potentiometer makes it very easy to calibrate for different surface colors. Highly recommended for beginners.

Good value but needs careful calibration
The module works well once you spend time tuning the potentiometer. It struggled a bit under direct sunlight, but indoors it tracks lines perfectly. Great price for a pack of these.

Essential for robotics kits
Bought these for a university project. They are robust and the output is clean. The LM393 comparator ensures stable switching between black and white surfaces.

Compact and effective
Small form factor fits easily on tight chassis designs. The IR emission is strong enough to detect lines even with a small gap. Very satisfied with the purchase.

Kids loved building the car
Easy to wire up with standard jumper cables. My kids successfully built a line-tracking car using these modules. The instructions online are plentiful which helped us get started quickly.

Reliable digital output
The digital output is very responsive. I wish it had an analog output option as well for more granular data, but for simple line following, this is exactly what is needed.
Q: Does this module come with mounting screws?
A: No, the module does not include mounting screws. It features standard 3mm holes, so you can use M3 screws and standoffs which are commonly available in electronics kits.
Q: Can this sensor work directly with a Raspberry Pi GPIO?
A: Yes, it can. Since the module operates at 3.3V to 5V and provides a digital output, it is compatible with Raspberry Pi GPIO pins. Just ensure you connect the VCC to the 3.3V or 5V pin accordingly.
Q: What is the maximum speed the robot can go while still tracking the line?
A: The sensor itself has a very fast response time. The limiting factor is usually your microcontroller's code efficiency and the motor driver's capability. Typically, hobby robots can track lines at speeds up to 0.5 meters per second reliably.
Q: Can this detect obstacles or only lines?
A: It can do both. While primarily designed for line tracking by detecting contrast, it can also function as a proximity sensor to detect obstacles within its 1-8mm range by reflecting IR light off the object.
Q: How do I adjust the detection range?
A: There is a blue potentiometer on the back of the PCB. Turn it clockwise to increase sensitivity (detect from further away) and counter-clockwise to decrease it. Use a small screwdriver to adjust while testing against your surface.
