Lowcost color recognition sensor module with low power consumption, small size and easy installation. How it works The onboard LED shines light on the measured object. The reflected light is captured and RGB ratio values are detected through a color filter. Color is identified based on the RGB ratio. Interfaces and compatibility Data can be read via serial UART (TTL level) or IIC (2wire). Compatible with microcontroller systems that support UART TTL or IIC interfaces. Key benefits Affordable solution for reliable color sensing in compact form. Low power consumption suitable for batterypowered or energyconscious setups. Easy to integrate due to simple optical principle and dual data interfaces. Practical applications Color sorting and quality control on production lines, where color categories determine handling or sorting steps. Color verification and matching in electronics assembly or packaging to ensure consistency. RGB color sensing for robotics, automation, or home automation projects that require colorbased decisions. Notes on performance and form Compact form factor enables easy integration into small enclosures or devices. Function relies on LED illumination and RGB ratio detection through a filter to classify colors. Supports two common communication methods to fit typical microcontroller workflows.
