Great for Beginners
Clear documentation helped me get started quickly. Sensitive to ambient light sometimes, but works great for intended STEM projects.

Reliable Line Tracking
Bought five for a sumo bot project. All sensors matched well in sensitivity. Great performance under indoor lighting conditions.

Easy to Integrate
Plug and play with my HelloSTEM board. No calibration headaches. The analog output gives fine control over line detection thresholds.

Good Value Sensor
Works well with Arduino. Wish the cable was a bit longer but otherwise solid. Calibration was straightforward using the potentiometer.

Perfect for Classroom Robots
Used these for our high school robotics club. Very consistent readings on black tape. The PH2.0 connector makes wiring clean and easy for students.
Q: Can this work with 3.3V logic microcontrollers?
A: Yes, it operates comfortably between 3.3V and 5V DC, making it safe for most modern boards.
Q: Does it work on colored lines or just black?
A: It is optimized for black lines on white surfaces. Contrast is key for accurate detection.
Q: Can I use this sensor outdoors?
A: It is best used indoors due to potential interference from direct sunlight.
