Excellent value
Bought 5 of these for a school project. All worked out of the box. Detection range is accurate.

Works but needs careful wiring
Functionality is fine, but the pins are not labeled clearly on the back. Make sure to check the schematic.

Good sensor, slight learning curve
The sensitivity is good once you adjust it properly. Took me a bit to get the line following right but hardware is solid.

Great for obstacle avoidance too
Not just for lines, I used it for proximity detection. Very responsive.
5 FAQ
Q: What is the maximum detection distance?
A: Typically up to 25mm depending on the surface reflectivity and potentiometer setting.
Q: Can I use this outdoors?
A: It is designed for indoor use. Strong sunlight may interfere with the IR sensor.
Q: What voltage should I supply?
A: Ideally 5V DC, but it operates safely between 3.3V and 5V.
Q: Does it output analog or digital signals?
A: This module outputs a digital signal (HIGH/LOW). The raw sensor is analog, but the LM393 converts it.
Q: Is this compatible with Raspberry Pi?
A: Yes, it works with Raspberry Pi GPIO pins operating at 3.3V logic.
