DFRobot Fermion: TCS3430 Tristimulus Color Sensor features advanced digital Ambient Light Sensing (ALS) and CIE 1931 tristimulus color sensing (XYZ). This sensor employs the new generation of TCS3430 spectral sensor IC. The sensor channels have a filter to control the optical response that allows the device to accurately measure ambient light and sense color. These measurements are used to calculate chromaticity, illuminance, and color temperature that are used to support various potential applications. The sensor operates at a 3.3V to 5V supply range and -30°C to 85°C operating temperature range. Typical applications include color detection, brightness detection, white balance detection, and color temperature measurement.
