RGB color model is an additive color model in which red, green and blue light are added together in various ways to reproduce a broad array of colors.
The name of the model comes from the initials of the three additive primary colors, red, green, and blue.
The keyestudio TCS34725 sensor mainly uses TCS34725 color sensor chip.
It can communicate with other controllers via I2C communication interface.
Keyestudio TCS34725 color sensor is a low cost, cost effective RGB full-color color recognition sensor.
The sensor can recognize the surface color of an object through optical sensing. The sensor is illuminated by bright light and outputs corresponding RGB values to help to restore the color.
Moreover, to avoid the surroundings interference and increase the accuracy, we particularly add an infrared light shielding plate on the sensor’s bottom, so that infrared spectrum element of incident light is minimized to make color management more accurate.
On the sensor bottom you can see 4 yellow highlight LEDs, which can ensure that the sensor can use normally under low ambient light, actually realizing the fill light function.
The sensor has high sensitivity, wide dynamic range, and infrared shading filter. It is an ideal color-sensitive component solution. It is widely used for RGB LED backlight control, solid-state lighting, health products, etc.
