Good value but needs careful mounting

The sensor is responsive and the five lines provide great resolution for smooth turning. Just make sure to mount it at the correct height, otherwise, it might miss the line occasionally.

Great for the price

For the cost, you really can't beat the performance. It's not industrial grade, but for hobby projects and educational robots, it is more than sufficient. Shipping was fast too.

Perfect for my line follower robot

This 5-channel sensor works flawlessly with my Arduino Uno. The ability to adjust sensitivity via the potentiometer made calibration very easy. It detects black tape on white surfaces instantly.

Excellent sensitivity range

I was worried about ambient light interference, but this module handles it well. The IR emitters are strong enough to work even in moderately lit rooms without false triggers.

Reliable and robust

We bought ten of these for our university lab. They have held up well under constant use by students. The digital output makes interfacing with microcontrollers straightforward.

Easy to integrate

The pinout is clearly labeled, and there are plenty of tutorials online for this specific TCRT5000L based module. Got my robot running in under an hour.

5 FAQ

Q: Is the output analog or digital?

A: This specific model provides a digital TTL output (HIGH/LOW) for each of the 5 channels. If you need analog values, please look for our analog version.

Q: What is the maximum speed a robot can track using this module?

A: The response time is very fast, typically allowing robots to track lines at speeds up to 1-2 meters per second, depending on your code logic and motor control.

Q: Can this sensor work outdoors in sunlight?

A: While the sensor has some resistance to ambient light, direct strong sunlight may interfere with the infrared detection. It is best used indoors or in shaded outdoor areas.

Q: Can I power this with 3.3V logic?

A: Yes, the operating voltage range is 3.3V to 5V, making it fully compatible with both 3.3V and 5V microcontroller systems like ESP32 and Arduino.

Q: Does this come with connecting wires?

A: No, the module comes as a standalone PCB. You will need to solder header pins or connect wires directly to the pads provided on the board.
