EL0406 MÓDULO RECONOCIMIENTO COLOR TCS230

Con este modulo es posible identificar el color que se ponga frente a ella, indicando la cantidad de Rojo (0-255) Verde (0-255) y Azul (0-255)

Características:
1.Chip: TCS230
2.Input voltage: DC 3V-5V,Output frequency voltage: 0 ~ 5V
3.Use bright white LED lights ,can be connected directly with Microcontroller ,Static detection of
the measured object color
4.Best detection distance: 10mm
5.Chip pins all has drawn for standard 100, put the needle (2.54 mm), mil-convenient for bitmap board
6. PCB size: 31.6 (mm) x24.4 (mm)
