Plug and play
Easy to interface with ADC. Documentation could be better but pinout is standard.

Good value
Accurate within the specified range. Struggles a bit with dark surfaces but overall good.

Range is limited
Works as described but 15cm is very short. Make sure this fits your project needs.

Reliable distance sensing
Used this for obstacle avoidance. Consistent readings indoors.
5 FAQ
Q: Is the output digital or analog?
A: This module provides an analog voltage output proportional to distance.
Q: Does it work in sunlight?
A: It has some immunity but direct sunlight may interfere with IR readings.
Q: Can I extend the wires?
A: Yes, but keep them short to avoid noise interference on the analog line.
Q: What is the pinout?
A: VCC, GND, and OUT from left to right when facing the sensor.
Q: Can I use this with 3.3V logic?
A: The sensor operates at 5V. Use a voltage divider for ADC input if using 3.3V MCU.
