Perfect for Arduino Robot
Works flawlessly with my Uno board. The potentiometer makes adjusting sensitivity easy. Great for line following projects.

Reliable Obstacle Detection
Used these for obstacle avoidance on my smart car. Response time is quick and no false positives so far.

Good value pack
Sensors work well. One had a slightly loose pin but I soldered it back. Detection range is accurate for the price.

Okay but sensitive to sunlight
Works great indoors. Struggles a bit in direct sunlight due to IR interference. Expected for this price point.
