Seamless integration

Plug and play with the standard Adafruit library. The color temperature and lux data outputs are a nice bonus feature that I didn't expect to use but found very useful.

Good value for money

For the price, you can't beat the performance. It's not industrial grade, but for hobbyist prototyping and educational purposes, it exceeds expectations. Fast shipping as well.

Ideal for university projects

Used this for a final year sorting machine project. It distinguishes between similar shades of blue and green very well. Documentation provided by the seller was helpful too.

Compact and reliable

Small form factor fits perfectly into my compact robot design. The integrated LED helps with lighting consistency, which was a pain point with previous sensors I used.

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.

Great sensor, minor library issues

The hardware quality is excellent and the readings are consistent. I had to tweak the example code slightly for my ESP32, but once configured, it works flawlessly for line following.

5 FAQ

Q: Can I disable the onboard LED to save power?

A: Yes, the integrated LED can be controlled via software commands through the I2C or UART interface, allowing you to turn it off when not in use to conserve energy.

Q: Is there a Python library available for Raspberry Pi?

A: Absolutely. This sensor is compatible with popular Python libraries such as smbus2 and specific TCS34725 wrappers available on GitHub and PyPI.

Q: Does it come with jumper wires included?

A: The package includes the sensor module and a set of male pin headers for soldering. Jumper wires are not included but can be purchased separately in our store.

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 as distance increases.

Q: Does this module work directly with 5V Arduino Uno without a logic level converter?

A: Yes, the GY-33 module includes an onboard voltage regulator and level shifting, making it safe to connect directly to 5V microcontrollers like the Arduino Uno.
