Description

The Grove I2C Color Sensor v2.0 utilizes a 4×4 array of filtered photodiodes (red, green, blue, and clear) paired with integrated 16-bit analog-to-digital converters. This architecture enables precise measurement of color chromaticity for both ambient light and reflected light from objects. The digital I2C output provides stable, noise-resistant data transmission.

Featuring a SYNC input, the module allows for synchronous integration cycles with external pulsed light sources, eliminating errors from ambient light fluctuations. Its wide operating temperature range and RoHS-compliant construction ensure reliable performance in industrial, educational, and prototyping applications requiring consistent color identification.

Frequently Asked Questions

What is the operating voltage range for the Grove I2C Color Sensor v2.0?

The sensor module operates from 3.3V to 5V DC. This dual-voltage compatibility allows it to interface directly with both 3.3V logic systems (like Raspberry Pi or ESP32) and 5V logic systems (like standard Arduino boards) without requiring a level shifter.

How do I connect and communicate with this sensor using I2C?

Connect the module's Grove connector to your microcontroller's I2C port (SCL and SDA pins). The sensor uses a standard I2C protocol; you can read its 16-bit registers for red, green, blue, and clear light intensity values. Libraries for Arduino and Python (for Raspberry Pi) are readily available from Seeed Studio Studio's repository to simplify data acquisition.

What is the purpose of the SYNC input pin on this color sensor?

The SYNC input pin allows you to synchronize the sensor's integration cycle with an external pulsed or modulated light source. This feature is critical for applications like barcode scanning or operating in environments with strong ambient light interference, as it ensures measurements are taken only during the active pulse of your controlled light source, improving accuracy.

Can this sensor distinguish between different colors or just light intensity?

Yes, it distinguishes colors. The TCS34725FN sensor uses separate red, green, and blue filtered photodiodes alongside a clear (unfiltered) photodiode. By comparing the 16-bit intensity values from each filtered channel, the module can accurately determine the chromaticity (color composition) of the detected light or reflected light from an object.
