Usage Tips: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 object Supports 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 color The color-sensitive photodiode integrates a chip and a localized infrared light-shielding filter to minimize the infrared spect component of the incident light, making color management more accurate High sensitivity, wide dynamic range, and infrared light-shielding filters make TCS34725 an ideal color-sensitive component solution under changing light conditions and through attenuation materials The TCS34725 color sensor has a wide range of applications, including RGBLED backlight control, solid-state lighting, health products, industrial process control, and medical diagnostic equipment Working voltage: 5V Maximum power: 0.5W Clock frequency: 0-400KHZ I2C address: 0X29 Current: 100MA Detection distance: 3-10MM Interface: IIC interface and 2.54 pitch interface Working temperature: -10°C to +50°C Specification:B:With Silicone shell/A:Without Silicone shell Colour:As Shown Material:B:PCB+Silicone/A:PCB Package Contents: 1 x Color Recognition Sensor Only 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.
