Perfect for my smart car project
Works flawlessly with my Arduino Uno. The sensitivity adjustment pot is very useful for different lighting conditions.

Good value but needs calibration
Solid sensor for the price. Had to spend some time calibrating the potentiometer for outdoor use.

Great sensitivity
Detects the black line on white background perfectly. Also tested on green tape and it responds well.

Easy to integrate
Plug and play with most microcontrollers. The digital output makes coding the line follower logic very simple.
