Introduction
The ambient light sensor can sense the surrounding light conditions and tell the processing chip to automatically adjust the brightness of the display backlight to reduce the power consumption of the product. For example, in handheld applications such as mobile phones, notebooks, GPS and other mobile devices, the display consumes up to 30% of the total battery power, and the use of ambient light sensors can maximize the battery's working time.
CQRTSL25911 Ambient light sensor integrates TSL25911FN chip, measures infrared plus visible light (wider range than TSL2561), features 600M: 1 wide dynamic range, Detects Light Intensity up to 88000Lux (Bright Sunlight), Controlled via I2C Interface, low power consumption. It is capable of operating across various light environment. Onboard voltage translator, compatible with 3.3V/5V operating voltage, Compatible with Raspberry Pi, Arduino, STM32 and other motherboards.
