This module is based on the TCS3472XFN color light digitizer as the core color sensor, the sensor provides red, green, blue (RGB) and clear light sensor value digital output. The integrated infrared blocking filter can minimize the infrared components of the incident light, and can accurately perform color measurement. It has high sensitivity, wide dynamic range and infrared blocking filter. Minimize the effects of R and UV components to produce accurate color measurements.Detection and maskable interrupts. Communication via I2C interface. This design is based on the same design principleThe design provides users with more for installation size and environment. The two-hole version is equipped with 2 LED lights to fill the object. This design provides sample programs for Ardunio and for STM32.Working voltage: 3.3V/5VLogic voltage: 3.3V/5vCommunication interface: 12CInterface Description:VIN: 3.3V/5V power supplyandGND: power ground-3V3: 3.3vSCL: 12C clock inputSDA: 12C data input: interrupt output (open drain output)LED: light emitting diodeColour:blackMaterial:PCBSize:31.3 x 11MMPackage Contents:1 x Color recognition sensor1 x straight pin1 x curved pinOnly the above package content, other products are not included.Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is 1-3cm. Note: Due to the light and screen setting difference, the item's color may be slightly different from the pictures. Please allow slight dimension difference due to different manual measurement. Sold by-Dadangjia
