The TSL2591 is a very-high sensitivity light-to-digital converter that transforms light intensity into a digital signal output capable of direct IC interface. It combines one broadband photodiode (visible plus infrared) and one infrared-responding photodiode on a single CMOS integrated circuit. Two integrating ADCs convert the photodiode currents into a digital output that represents the irradiance measured on each channel. This digital output can be input to a microprocessor where illuminance (ambient light level) in lux is derived using an empirical formula to approximate the human eye response. The TSL2591 supports a traditional level style interrupt that remains asserted until the firmware clears it.

Adopts TSL25911FN, measures infrared plus visible light (wider range than TSL2561). Embedded ADC, direct light intensity signal output to I2C interface, less noise jamming. High sensitivity up to 188uLux, wide dynamic range up to 600M:1. Embedded infrared-responding photodiode allows precise measuring even in strong infrared noise environments. Provides interrupt output with programmable upper and lower thresholds. Onboard voltage translator, compatible with 3.3V/5V operating voltage. Comes with development resources and manual (examples for Raspberry Pi/Arduino/STM32).
