Gravity: TCS3430 Tristimulus Color Sensor

Devices equipped with True Tone technology, such as Apple iPad Pro, iPhone, and Macs, typically have sensors to measure ambient light color and brightness. These devices then use this data to automatically adjust their displays, correcting white points and illumination according to the environmental lighting to render the perfect white under any conditions. The XYZ Tristimulus Color Sensor is crucial in this technology. The TCS3430 features advanced digital ambient light sensing (ALS) and CIE 1931 tristimulus color sensing (XYZ). The CIE1931 XYZ Tristimulus model is a standard based on three different human cone cell types. The CIE XYZ color space covers all visible color sensations for those with average eyesight. The TCS3430's spectral response is nearly identical to that of human eyes, enabling high - precision measurement of illumination and color temperature. It truly offers 'what you see is what you measure'. This sensor is perfect for smartphone applications to enhance color measurement and ambient light intensity assessment. It's also great for scenarios demanding a true - color viewing experience, like online shopping, where it helps with product color matching and reduces return rates due to color differences between images and real products. Features include an XYZ Tristimulus Filter, ±10% illuminance and correlated color temperature accuracy, a wide dynamic range, high sensitivity, and programmable gain and integration time. Applications range from color, brightness, and white balance detection to color temperature measurement. Specifications are a power supply of 3.3V - 5V, an operating current of <5mA, an LED operating current of <15mA, an I2C address of 0x39, an operating temperature range of - 30°C - 85°C, and dimensions of 22*27mm/0.87*1.06”.

Using the Gravity TCS3430 Tristimulus Color Sensor is easy. First, connect it to your device using the provided Gravity - 4P I2C/UART Sensor Connector. Make sure your device's power supply is within the 3.3V - 5V range. Once connected, the sensor will start measuring ambient light color and brightness automatically. For smartphone applications, simply integrate it into your phone's system to enhance color measurement. In online shopping scenarios, use it to ensure accurate color matching of products. When it comes to maintenance, keep the sensor in a dry place and within the operating temperature range of - 30°C - 85°C. Avoid exposing it to extreme heat or moisture. Also, be careful not to exceed the maximum operating current limits of <5mA for normal operation and <15mA for the LED.
