Does the job

Range is accurate after calibration. Cables could be longer for some setups but easily extendable.

Reliable obstacle detection

Used five of these for a line follower project. All consistent. Great value for the price point.

Good sensor, slight light interference

Works well indoors. Sunlight affects it a bit outdoors so keep that in mind for outdoor projects. Otherwise solid.

5 FAQ

Q: Can I use this in direct sunlight?

A: Strong ambient light may interfere with IR detection accuracy. Shielding is recommended for outdoor use.

Q: Does it detect clear glass objects?

A: Infrared sensors generally struggle with transparent objects like glass due to light passing through.

Q: Is the output analog or digital?

A: This module provides a digital TTL output signal indicating presence or absence.

Q: How do I change the detection distance?

A: Use the blue potentiometer on the back of the module to adjust sensitivity and range.

Q: Can this work with 3.3V logic microcontrollers?

A: It operates at 5V, but the output signal may interface with 3.3V MCUs. Check your specific board tolerance.
