Ocean: TSL25911FN Ambient Light Sensor for Raspberry Pi, Arduino and STM32.

AMS' TSL2591 device series provides a wide 600M:1 dynamic range, up to 88,000 lux (bright sunlight), which improves design flexibility and provides engineers with ambient light sensors and a variety of non-display performance display applications.

TSL2591 is an ultra-high sensitivity optical digital converter that can convert light intensity into digital signal output with a direct I 2 C interface. The device integrates a broadband photodiode (visible light and infrared light) and an infrared response photodiode on a single CMOS integrated circuit. Two integrating ADCs convert the photodiode current into a digital output, which represents the irradiance measured on each channel. This digital output can be input to a microprocessor, where an empirical formula is used to derive the brightness (ambient light level) in lux to approximate the response of the human eye. TSL2591 supports traditional level-style interrupts and remains valid until the firmware is cleared.

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.
