VEML3328

VEML3328 is a RGBCIR colour sensor with I²C interface. This sensor senses red, green, blue, clear, and IR light by incorporating photodiodes, amplifiers, and analogue / digital circuits into a single CMOS chip. With this sensor, the brightness and colour temperature of a display backlight can be adjusted based on the ambient light source, and it can differentiate indoor from outdoor lighting environments. Suitable for automatic white balancing and colour cast correction in digital cameras, automatic LCD backlight adjustment, maintaining consistent true colour and ideal brightness levels on handheld displays as users move between indoor and outdoor environments, on / off light switching in industrial and consumer applications, active monitoring of LED colour output for IoT and smart lighting.
