Product Description
The WH26533 is a low-power, high-sensitivity color light sensor with an I2C interface.This color sensor detects red, green, blue, white (RGBW), and clear channels and converts them to digital values. The RGBW sensor is designed to suppress infrared radiation from light sources, enabling the device to operate normally under various conditions from direct sunlight to dark environments.
The WH26533 can extract light flicker frequency to enhance the shooting experience and eliminate banding effects. Its selectable range allows users to optimize sensitivity based on ambient light illuminance and color temperature, thereby adjusting the LCS backlight brightness of TVs, phones, and tablets.
The WH26533 operates over a supply voltage range of 1.7V to 2.0V. The device provides software shutdown mode control for energy-saving applications.
