Lowcost color sensor module with compact form factor, low power consumption, and easy installation. Working principle The LED emits light to illuminate the object and the sensor detects the reflected light to determine colors by analyzing the RGB ratio values. Dual data reading Serial UART and I2C communication formats are supported, providing flexible integration with a wide range of microcontrollers and development boards. Adjustable LED brightness LED brightness can be adjusted to optimize color recognition for different lighting conditions and applications. Key benefits Low power operation suitable for battery powered projects Small footprint for easy mounting in tight spaces Flexible data interfaces (UART and I2C) for broad compatibility Adjustable illumination to improve color accuracy across environments What makes it stand out Simple installation with a compact module design Direct RGB based color identification via reflective sensing Two common communication protocols enable quick integration with existing systems Specifications and compatibility highlights Function: Color sensing via RGB ratio using an illumination LED Interfaces: Serial UART and I2C Size: Compact form factor designed for easy mounting Performance: Low power consumption with adjustable LED brightness Application scope: Works with controllers and boards that support UART or I2C Use scenarios Color sorting and quality control on a production line or recycling stream Color matching and calibration for displays, printers, or LED lighting systems Educational projects and prototyping with common microcontrollers such as Arduino or Raspberry Pi This description preserves the original product features and functions while presenting them in clear, customerfriendly language with practical use cases.
