The Fermion: TCS3430 Tristimulus Color Sensor is a high-performance, compact module designed for precise ambient light sensing and true color detection. Featuring XYZ Tristimulus technology based on the CIE 1931 color space, this sensor closely replicates the way the human eye perceives light and color—making it ideal for advanced applications that require accurate illuminance and color temperature measurement.
What is Tristimulus Sensing?
Devices like the iPhone, iPad Pro, and Macs use True Tone technology, powered by sensors that adjust white balance based on your environment. The TCS3430 plays a key role in enabling this by measuring ambient light using XYZ Tristimulus filters that mimic human vision. The result? "What you see is what you measure"—a perfect fit for color-critical tasks.
