Seeed Studio Grove I2C Color Sensor V2 RGB LED Control

SKU CH-GMMM-M8NH7

I2C colour sensor with 16-bit digital output, programmable interrupt and 2.5 µA sleep current for low-power RGB detection

  • Product typeSensors
  • Accurate color detection with 16-bit digital I2C output at 400 kHz
  • Low 2.5 µA sleep current extends battery life in portable projects
  • Maskable interrupt triggers only when color crosses your set thresholds
  • Grove unified socket gives instant plug-and-play connectivity
  • TCS34725FN sensor measures ambient light or object color via reflective sensing

Grove I2C Color Sensor V2

The Seeed Studio Grove I2C Color Sensor V2 is a plug-and-play module for accurate colour and light sensing. It uses the TCS34725FN sensor with a 3x4 array of filtered photodiodes and 16-bit ADC converters. Digital output runs over I2C at 400 kHz. A sleep current of 2.5 µA keeps average power consumption low.

Makers needing colour detection

This module suits developers adding colour recognition or ambient light measurement to microcontroller projects. The Grove unified socket allows direct connection without soldering. It is not suited for applications requiring spectral analysis beyond RGB and clear channels. Buyers needing higher-speed interfaces or built-in lenses should evaluate alternative sensor types.

16-bit I2C digital output

The sensor provides 16-bit digital RGBC data via a standard I2C bus at 400 kHz. Programmable upper and lower thresholds drive a maskable interrupt pin for event-driven designs. Synchronisation input supports external pulsed light sources. This output format determines compatibility with host controllers and software libraries.

Questions about this item

How does the 16-bit digital output translate to colour accuracy in a project?

The 16-bit ADC on the TCS34725FN provides fine-grained RGBC data, letting you distinguish subtle hue and brightness differences for tasks like display backlight tuning or object colour sorting.

What does the 400 kHz I2C rate mean for real-time reading speed?

At 400 kHz the sensor can stream 16-bit colour samples fast enough for responsive ambient-light adjustment or LED feedback loops without bus congestion.

How does the Grove socket affect mounting and wiring?

The unified Grove connector gives a keyed, solderless plug-in that locks into any Grove base shield or cable, so the module sits securely without custom PCB work.
