Sensitive adjustment needed
Works well once you tune the potentiometer. Ambient light can affect it slightly, but shielding helps during operation.

Good value sensor
Does what it says. Detection range is short but accurate for line following. Just ensure you power it correctly within the voltage limits.

Perfect for my line follower
Worked straight out of the box. Connected to my Arduino Uno and the sensitivity potentiometer made calibration easy. Highly recommend for beginners.

Reliable and sturdy
The PCB quality is good. Soldering points are clear. Used it for obstacle avoidance on a small car chassis without issues.

Great for school projects
Bought five for a robotics competition. All worked perfectly. The output LED is very helpful for debugging logic issues.
Q: Is the output analog or digital?
A: This module provides a digital switching output (HIGH/LOW).
Q: How do I adjust the sensitivity?
A: Use the blue potentiometer on the board. Turn it clockwise or counter-clockwise while testing the output.
Q: Does it come with jumper wires?
A: No, the package includes only the sensor module. Wires are sold separately.
Q: What is the maximum detection range?
A: The effective detection range is typically between 1mm to 8mm depending on surface reflectivity.
Q: Can this work with a 3.3V microcontroller?
A: Yes, the module supports 3.3V to 5V input voltage comfortably.
