The Gravity: TCS3430 Tristimulus Color Sensor is a high-precision color sensor module designed for accurate ambient light sensing and true-color detection, using advanced CIE 1931 XYZ Tristimulus technology. This XYZ sensor plays a key role in True Tone displays, like those found in the Apple iPad Pro, iPhone, and Macs, which automatically adjust screen brightness and color balance based on the ambient light sensor data.

Advanced Color Sensing with Human-Eye-Like Accuracy

Powered by the TCS3430 color sensor, this module integrates digital ambient light sensing (ALS) and XYZ color sensing, closely simulating the human eyes spectral response. Based on the CIE 1931 color space, this XYZ sensor allows for high-accuracy measurements of illuminance and color temperature, making it ideal for Arduino color sensor projects and other color-sensitive applications.

What you see is what you measure the TCS3430 color sensor delivers dependable and repeatable results for accurate ambient light sensor readings.
