The TCS34725 is an I2C RGB colour sensor that detects the red, green, and blue components of light in its environment and returns digital colour values. With high sensitivity, a wide dynamic range, and a built-in IR blocking filter, it delivers accurate colour readings under varied lighting conditions.
Four on-board ultra-bright LEDs illuminate the target surface, so the sensor works reliably without external lighting. The module connects via I2C and includes both PH2.0-4P and XH2.54 (breadboard) interfaces for flexible wiring options.

Jargon buster
Plain-language definitions for the technical terms used above.
- dynamic range
- Dynamic range describes how wide a span of values a sensor can measure, from very low to very high. For a light sensor, a wide dynamic range means it can work in dim indoor settings as well as bright sunlight without changing hardware.
- Headers
- Rows of connector contacts on a fixed pitch (commonly 2.54 mm) used to link a board to a breadboard, jumper wires, or another board. They come as male pin headers and female socket headers; when a module ships with pre-soldered headers it can be used straight away, whereas bare pads require soldering the pins yourself.
- I2C
- I2C is a two-wire communication bus used by many sensors and small modules. It matters because several I2C devices can share the same two wires, but each device needs a compatible address and your controller must support I2C.
- LED
- A light-emitting diode (LED) is a small electronic component that emits light when current flows through it in the correct direction. Because it only conducts one way, its polarity matters, and a through-hole LED must be soldered the correct way around to light up.
- RGB
- Short for red, green and blue, the three primary colours of light that are mixed in varying amounts to make a wide range of colours. In electronics RGB can refer to an LED or pixel that blends these three colours, or to a colour signal or interface that carries separate red, green and blue channels.
