Frequently Asked Questions
Frequently Asked Questions
Is it compatible with Arduino Uno?
Yes.
Does it work with ESP32?
Yes.
Can the sensing distance be adjusted?
Yes.
The onboard potentiometer allows adjustment of the detection range.
Does it detect transparent objects?
Detection performance depends on the object's material, color, and surface reflectivity. Transparent or highly reflective objects may behave differently.
Can it detect black objects?
Yes, but the sensing distance may be reduced because black surfaces reflect less infrared light.
Is the output analog?
No.
This module provides a digital output.
Can it be used for line follower robots?
It is primarily designed for obstacle detection. Dedicated line tracking sensors generally provide better performance for line follower applications.
Is it suitable for beginners?
Yes.
It is one of the easiest sensors to interface with Arduino.
