Good sensor, slight learning curve
Quality is good. Had to adjust the threshold potentiometer initially to get stable readings.

Solid component
Good build quality. Wish the connecting cables were a bit longer included in the package.
Q: Does it come with the code library?
A: It is hardware only, but sample code and documentation are available on our website download section.
Q: Is this compatible with 5V Arduino Uno?
A: Yes, it operates within 3.3V to 5V DC range and is fully compatible with Arduino Uno.
Q: Can I use this outdoors?
A: It is designed for indoor use; direct sunlight may interfere with IR sensor accuracy.
Q: What is the maximum RPM it can measure?
A: Depends on the disc slots, but the sensor response time supports high speeds up to several thousand RPM.
Q: How many wires does it need?
A: It requires 3 connections: VCC, GND, and Signal Output for proper functionality.
