Reliable batch purchase

Ordered ten of these for our makerspace. All units arrived in perfect condition and performed identically. The built-in LEDs provide consistent illumination.

Works well but sensitive to distance

It detects colors accurately, but the distance from the object matters a lot. I had to 3D print a shroud to block ambient light for best results.

Perfect for Arduino color sorting projects

This module worked flawlessly with my Arduino Uno. The library support is excellent, and it accurately distinguishes between primary colors. Great value for the price.

Fast response time

Impressed by how quickly it updates the frequency output. Ideal for conveyor belt applications where speed is necessary. Highly recommended.

Good sensor, needs calibration

The hardware is solid, but you definitely need to spend time calibrating it for your specific lighting conditions. Once set up, it reads RGB values consistently.

Great for learning embedded systems

Bought this for a university project. The documentation online is plentiful, making it easy to get started. The frequency output is easy to read with micros().

5 FAQ

Q: Can this sensor detect transparent objects?

A: This sensor is designed to detect reflected light from opaque surfaces. It cannot reliably detect transparent or highly reflective materials like clear glass or mirrors.

Q: Do I need to solder the pins before using it?

A: The module comes with a separate pin header strip. You will need to solder them onto the PCB yourself unless you choose to use jumper wires temporarily for testing.

Q: Does this module work directly with 3.3V logic boards like ESP32?

A: Yes, the module operates between 2.7V and 5.5V, so it is fully compatible with 3.3V systems like the ESP32 without needing a level shifter.

Q: What is the maximum distance for accurate color reading?

A: For optimal accuracy, the object should be within 3mm to 10mm of the sensor surface. Accuracy decreases significantly beyond this range due to light dispersion.

Q: Is there a library available for MicroPython?

A: While we do not provide an official MicroPython library, several open-source community drivers are available on GitHub that work well with this module.
