Reliable and compact
We purchased ten of these for our workshop. All units performed consistently. The form factor is small enough to fit into tight enclosures without sacrificing performance.

Ideal for university projects
Bought this for a sorting robot project. It distinguishes between similar shades of blue and green very well. The documentation provided by the seller was helpful too.

Perfect upgrade from TCS3200
This module is significantly easier to use than the older TCS3200. The I2C interface saves so many GPIO pins on my Arduino project. Color accuracy is impressive right out of the box.

Fast shipping and great product
Arrived quickly and well-packaged. Integrated it into a home automation system to detect liquid colors in transparent tubes. No false readings so far.

Great sensor, minor library issues
The hardware quality is excellent and the white LED provides consistent lighting. I had to tweak the example code slightly for my ESP32, but once configured, it works flawlessly.

Good value for money
Works as advertised. The color temperature reading is a nice bonus feature. Just ensure your pull-up resistors are correctly sized for your I2C bus speed.
Q: What is the maximum distance for accurate color detection?
A: For optimal accuracy, we recommend placing the object within 10mm to 20mm of the sensor. While it can detect up to 60mm, precision decreases with distance.
Q: How do I calibrate the sensor for different lighting conditions?
A: You can adjust the integration time and gain settings via the I2C registers to suit ambient lighting. For best results, perform calibration in the specific environment where the sensor will be used.
Q: Does this module work directly with 5V Arduino Uno boards?
A: Yes, the GY-33 module supports an operating voltage range of 3.3V to 5V, making it fully compatible with the 5V logic of the Arduino Uno.
Q: Is a library available for MicroPython?
A: Yes, several open-source MicroPython libraries are available on GitHub that support the TCS34725 chip used in this module.
Q: Can this sensor detect UV light levels?
A: This sensor is designed for visible color recognition (RGB) and clear light detection. It includes a UV filter to improve color accuracy, but it does not measure UV intensity specifically.
