keyestudio TCS34725 Color Sensor RGB color Sensor Module For Arduino

The Keyestudio TCS34725 Color Sensor is a highly sensitive, cost-effective RGB colour recognition module designed for Arduino and other microcontrollers. It is ideal for students, makers, and hobbyists looking to add precise optical colour sensing to their robotics and automation projects. With integrated fill lights and an infrared filter, it delivers accurate colour readings even in challenging lighting conditions.

Optical colour recognition

The module uses the TCS34725 colour sensor chip to recognise the surface colour of objects through optical sensing. It illuminates the target and outputs corresponding RGB values to help restore and identify the exact colour.

Integrated infrared shielding

To prevent environmental interference and improve measurement accuracy, the sensor features an infrared light shielding plate on the bottom. This minimises the infrared spectrum element of incident light, ensuring more precise colour management.

Low-light fill illumination

Four yellow highlight LEDs are built into the bottom of the board to act as a fill light. This ensures the sensor can function normally and capture accurate readings even in low ambient light environments.

Versatile application potential

With its high sensitivity and wide dynamic range, this sensor is an ideal choice for diverse projects. It is commonly used for RGB LED backlight control, solid-state lighting systems, and health-related products.

I2C communication interface

The module communicates with your main controller via a standard I2C interface. This simplifies wiring and integration with Arduino boards and other compatible microcontrollers.

Technical specifications

Operating at 3.3-5V with a low current draw of 65uA, the sensor measures distances from 3mm to 10mm. It features a 2.54mm pin pitch, weighs just 3.5g, and operates reliably in temperatures from -30 to +70 degrees Celsius.
