Exceeded expectations

I was skeptical about using a CCD for line tracking, but the speed and accuracy are impressive. The dynamic thresholding really makes a difference on uneven surfaces.

Great for university competitions

We used this for our national robotics contest. It allowed our car to navigate complex tracks with sharp turns easily. Documentation was clear and setup was quick.

Solid performance in indoor lighting

Works great under controlled indoor lighting. I noticed some noise when testing directly under bright sunlight, but adding a simple shield fixed the issue immediately.

Reliable and consistent

Bought five of these for our workshop. All units performed consistently right out of the box. The linear array gives a much wider field of view compared to point sensors.

Good resolution, needs careful wiring

The 128-pixel resolution provides excellent detail for track detection. Just ensure your clock signal is stable, or you might get noisy data. Overall a solid sensor for the price.

Perfect for autonomous car projects

This TSL1401 module works flawlessly with my Arduino-based line follower. The dynamic threshold algorithm handles varying light conditions much better than simple IR sensors.

5 FAQ

Q: Does this come with example code for Arduino?

A: The package includes a link to a GitHub repository with basic Arduino libraries and example sketches to help you get started with data acquisition.

Q: What is the maximum scanning speed supported?

A: The TSL1401 can operate with a clock frequency up to 10 MHz, allowing for very high line scan rates suitable for fast-moving robotic applications.

Q: Can it detect colored lines or only black on white?

A: It detects contrast differences. While optimized for black lines on white surfaces, it can detect other color combinations provided there is sufficient luminance contrast.

Q: Is this module compatible with Raspberry Pi GPIO?

A: Yes, it is compatible. You will need to write a script to handle the serial clock and data lines via the GPIO pins. Many users have successfully interfaced it using Python.

Q: What is the power consumption of this module?

A: The module typically draws around 20mA to 30mA at 5V during active scanning, making it suitable for battery-powered mobile robots.
