Sensitive to ambient light
It works well indoors, but when I took my robot outside, the sunlight interfered with the sensor readings. You might need to build a small shield around it for outdoor use.

Solid performance for the price
For the cost, you really can't beat this module. It handles both line tracking and simple obstacle detection well. Just ensure your power supply is stable.

Good value but needs careful mounting
Works great for obstacle avoidance. You need to mount it at the exact right height though, or the range varies too much. Once positioned correctly, it is very reliable.

Fast response time
I used this for a high-speed line follower. The response time is incredibly fast, allowing my car to take sharp corners without falling off the track. Highly recommended.

Compact and lightweight
The small form factor is perfect for my micro racing car. It didn't add significant weight, and the pinout is standard enough to connect directly to my microcontroller.

Perfect for my sumo bot
The sensitivity adjustment potentiometer makes it very easy to calibrate for different surface colors. It detected the black line on my white track immediately without any lag.
Q: Is there a library available for Arduino?
A: While there isn't a dedicated library required, the sensor outputs a simple digital HIGH/LOW signal that can be read using the standard digitalRead() function in Arduino IDE.
Q: How do I adjust the detection distance?
A: There is a blue potentiometer on the PCB. Use a small screwdriver to turn it clockwise to increase sensitivity (distance) or counter-clockwise to decrease it.
Q: Can this sensor detect clear glass obstacles?
A: This sensor relies on diffuse reflection, so it may struggle with transparent objects like clear glass as they do not reflect enough light back to the receiver.
Q: What is the maximum current consumption of this module?
A: Under normal operating conditions with the LED active, the module typically consumes around 20mA to 30mA.
Q: Can I connect multiple sensors to one microcontroller?
A: Yes, you can connect as many as you have digital input pins for. Just ensure you share the VCC and GND lines properly across all modules.
