Great for line following too
Bought these for my robot car kit. Obstacle avoidance works well. I also tested them for line following and they are versatile.

Perfect for Arduino Projects
Works exactly as described. Easy to calibrate with the potentiometer. I used it for a small obstacle avoidance robot and it responded quickly.

Good value
Solid sensor for the price. Range is decent indoors. Had to tweak the sensitivity slightly but once set, it was reliable.

A: It has a 3-pin interface: VCC, GND, and OUT.
Q: Is this suitable for outdoor use?
A: Strong sunlight may interfere with IR sensors. It is best suited for indoor or shaded environments.
Q: Can this work with 3.3V logic?
A: Yes, it supports 3.3V to 5V input voltage and logic levels.
Q: How do I adjust the detection distance?
