This module mainly uses the TCS34725 color sensor. TCS34725 is a low-cost, cost-effective RGB full-color color recognition sensor. The sensor uses optical sensing to identify the surface color of an objectSupports red, green, and blue (RGB) three primary colors, supports bright light sensing, and can output the corresponding specific values to help you restore the true colorThe color-sensitive photodiode integrates a chip and a localized infrared light-shielding filter to minimize the infrared spectrum component of the incident light, making color management more accurateHigh sensitivity, wide dynamic range, and infrared light-shielding filters make TCS34725 an ideal color-sensitive component solution under changing light conditions and through attenuation materialsThe TCS34725 color sensor has a wide range of applications, including RGBLED backlight control, solid-state lighting, health products, industrial process control, and medical diagnostic equipmentWorking voltage: 5VMaximum power: 0.5WClock frequency: 0-400KHZI2C address: 0X29Current: 100MADetection distance: 3-10MMInterface: IIC interface and 2.54 pitch interfaceWorking temperature: -10°C to +50°CSpecification:B:With Silicone shellColour:As ShownMaterial: B:PCB+SiliconePackage Contents:1 x Color Recognition SensorOnly 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.
