Excellent for school projects
Bought this for a university robotics competition. The response time is fast, and the digital output makes interfacing with microcontrollers very simple. Great product!

Solid hardware, standard library support
Hardware quality is good for the price. It works with most standard line-following libraries available online. The only downside is the short connector wires included.

Easy to use for kids
My son used this for his science fair project. The instructions were clear enough that he could wire it up himself. The LED indicators are helpful for troubleshooting.

Perfect for my Arduino robot car
This sensor module works flawlessly with my Arduino Uno project. The sensitivity adjustment potentiometer makes it very easy to calibrate for different track colors. Highly recommended for beginners.

Works well in controlled lighting
The sensor performs well indoors under artificial light. However, I noticed some interference when testing it in direct sunlight. Make sure to shield it if using outdoors.

Good value but needs careful calibration
The 5-channel version provides great resolution for line following. It took a little time to get the height and sensitivity just right, but once set up, it tracks lines smoothly.
Q: Is this compatible with Raspberry Pi GPIO pins?
A: Absolutely. Since the output is digital TTL level, you can connect it directly to the GPIO pins of a Raspberry Pi. Just ensure you match the voltage levels (3.3V or 5V).
Q: Does the package include mounting screws?
A: The module comes with mounting holes sized for standard M3 screws, but screws are not included in the package. You will need to source those separately.
Q: What is the maximum speed the car can go while tracking?
A: The tracking speed depends on your motor setup and code optimization, but the sensor's response time is generally fast enough for speeds up to 1-2 meters per second in typical hobbyist applications.
Q: Can this sensor detect black lines on a white surface?
A: Yes, this infrared sensor is specifically designed to detect the contrast between black lines and white surfaces, which is standard for line-following robots.
Q: Can I use two of these sensors on one microcontroller?
A: Yes, you can use multiple sensors on one microcontroller. Just connect each sensor's output pin to a different digital input pin on your board and power them in parallel.
