This TCS34725 Color Recognition Sensor Module is a powerful assistant for your electronics projects and product development.At its core, it features the original TCS34725FN chip from AMS, a digital color sensor that integrates RGB filters and an IR blocking filter, delivering exceptional color measurement accuracy and consistency. The module outputs clear red, green, blue, and clear channel data via the I2C digital interface, allowing your microcontroller to easily 'see' and distinguish colors.To address insufficient ambient light, the module is specially designed with a high-brightness white LED as a fill light. Its standout feature is that the LED brightness can be manually adjusted continuously via an onboard potentiometer or programmatically controlled via a PWM signal from the microcontroller. This means you can flexibly adjust the fill light intensity based on the actual application scenario—whether in dim indoor settings or bright outdoor environments—to always achieve optimal color recognition results, effectively avoiding detection errors caused by light variations.In terms of compatibility, the module adopts a 3.3V/5V dual-voltage logic design and comes with a standard 4Pin interface (VCC, GND, SDA, SCL), allowing seamless connection to almost all popular development platforms such as Arduino Uno/Mega, Raspberry Pi, ESP8266/ESP32, and Micro:bit. We provide comprehensive Arduino example codes and Python libraries, enabling even beginners to complete wiring and read color data within minutes, significantly shortening the development cycle.The module's circuit board is meticulously designed with a compact layout (typically around 20mm x 20mm) and integrates necessary level shifting and power filtering circuits, ensuring signal purity and operational stability. It boasts strong anti-interference capability, making it ideal for integration into industrial sorting equipment, smart home color-sensing lighting, educational robot vision systems, or personalized color-interactive art installations that demand high reliability.Whether for learning the principles of color sensing or developing professional color sorting machines, ambient light-adaptive screens, or smart color-tuning lights, this feature-rich and easy-to-use TCS34725 Color Sensor Module is your ideal choice.
