5 FAQ
Q: Does this work with Arduino Uno?
A: Yes, it is compatible with 5V microcontrollers like Arduino Uno.
Q: Can I use this in direct sunlight?
A: Outdoor use is not recommended as sunlight interferes with infrared detection.
Q: Is the cable detachable?
A: No, the wires are directly connected to the sensor module housing.
Q: What happens when an object is detected?
A: The output signal goes low for NPN configuration when an obstacle is sensed.
Q: Is there a potentiometer for adjustment?
A: Yes, there is a trimmer pot on the back to adjust detection distance.
