Exactly as described
Non-infrared feature is great for avoiding interference from other sensors. Direct digital output makes interfacing with MCU very simple.

Decent module
Documentation was a bit sparse, had to test pins manually to map the channels. Sensor itself works fine once you figure out the pinout.

Great value
Fast response time compared to standard IR sensors. Successfully used it for a black line on white background and vice versa. Highly recommend for DIY.

Good sensitivity
Works well but needs precise height adjustment from the ground. Once calibrated, it tracks colored lines accurately. Good value for the price.

Perfect for RoboContest
Used this for our university line follower robot. The 8 channels provide excellent resolution for smooth turns. No infrared interference was a huge plus in the arena.
Q: What is the optimal height from the ground?
A: Typically 5mm to 10mm works best for accurate detection. You may need to adjust based on your specific chassis design.
Q: Does this require external pull-up resistors?
A: No, the module has onboard comparators and circuitry. You can connect the output pins directly to your microcontroller GPIO.
Q: Is there an onboard microcontroller?
A: No, this is a pure sensor module without an MCU. It is designed to be controlled by an external processor like Arduino or STM32.
Q: Can it distinguish between blue and green lines?
A: Yes, the grayscale sensor detects contrast differences. It is calibrated to recognize various colors including blue and green against contrasting backgrounds.
Q: Is this compatible with Arduino Uno?
A: Yes, it outputs digital TTL signals which are fully compatible with Arduino Uno and most 3.3V/5V microcontrollers.
