Solid performance under varying light
We tested these in our makerspace under different lighting conditions. They perform well, though direct sunlight can interfere slightly. Indoor use is perfect. Good build quality.

Perfect for my Arduino line follower
These sensors work flawlessly with my Arduino Uno project. The sensitivity adjustment via the potentiometer makes it easy to calibrate for different surface colors. Very reliable detection range.

Compact and responsive
The form factor is small enough to fit on tight chassis designs. Response time is quick, which is crucial for high-speed obstacle avoidance. Highly recommended for beginners.

Reliable and easy to wire
Pinout is standard and easy to understand. The LED indicators are bright and helpful for debugging without needing a serial monitor. Will definitely buy more for future projects.

Good value but needs careful calibration
Great little module for the price. It took me a few minutes to get the distance just right for my specific track, but once calibrated, it tracks lines very smoothly. Just ensure your voltage matches.

Essential for robotics class
Bought a pack of five for our university robotics competition. All units worked out of the box. The digital output makes interfacing with microcontrollers incredibly simple.
Q: Can I use this for liquid level detection?
A: While technically possible due to reflection changes, this sensor is optimized for solid surface tracking. For liquids, specialized fluid sensors are recommended for better accuracy and safety.
Q: Does the package include mounting screws?
A: No, the package includes only the sensor modules. Mounting screws are not included, but standard M3 screws fit the 3mm mounting holes perfectly.
Q: What is the maximum effective detection distance?
A: The effective detection range is typically between 1mm and 25mm. Beyond 25mm, the reliability decreases significantly depending on ambient light and surface reflectivity.
Q: Can this sensor detect black lines on a white surface?
A: Yes, the TCRT5000 is specifically designed to detect contrast differences, making it ideal for tracking black lines on white backgrounds by adjusting the sensitivity potentiometer.
Q: Is this compatible with Raspberry Pi GPIO pins?
A: Absolutely. Since the module operates at 3.3V to 5V and provides a digital output, it can be directly connected to Raspberry Pi GPIO pins without additional level shifting.
