Solid performance
Works well for general color detection. Note that it needs to be relatively close to the object (within 10mm) for the most accurate readings, which is expected for this type of sensor.

Good value, minor wiring confusion
The module itself is great and reads colors quickly. I lost one star because the pin labeling on the back was a bit faint, but once I found the correct I2C pins, it worked perfectly.

Excellent sensitivity
I used this to sort M&Ms by color in a university project. The 16-bit resolution allows for very fine distinctions between similar shades. Highly recommended for students.

Plug and play
Arrived quickly and worked out of the box. The example code provided in standard libraries makes getting started trivial. Great addition to any sensor kit.

Great learning tool
As someone new to electronics, this was a fun module to experiment with. The community support for TCS34725 is huge, so finding help was easy. Very satisfied.

Perfect for my robotics project
This sensor works flawlessly with my Arduino Uno. The color recognition is surprisingly accurate even under varying light conditions thanks to the built-in LED. Setup was easy using the Adafruit library.
Q: Is the white LED always on?
A: No, the integrated white LED is programmable. You can control its intensity or turn it off completely via code to save power or prevent interference with ambient light readings.
Q: What library should I use for this sensor?
A: We recommend using the Adafruit_TCS34725 library, which is available directly in the Arduino Library Manager. It provides easy-to-use functions for reading RGB values and clear channel data.
Q: Can this detect colors through glass or plastic?
A: The sensor can read colors through thin, transparent materials, but accuracy may decrease depending on the tint and thickness of the material. Direct line of sight yields the best results.
Q: What is the maximum I2C clock speed supported?
A: The TCS34725 supports standard mode (100 kHz) and fast mode (400 kHz) I2C communication speeds. Ensure your pull-up resistors are appropriate for your bus speed.
Q: Does this module work with 5V Arduino boards like the Uno?
A: Yes, the module includes a voltage regulator and level shifting, making it fully compatible with both 3.3V and 5V logic systems including the Arduino Uno.
