Datasheet - Apr. 2013 - ams163.5

The TSL2591 is a very-high sensitivity light-to-digital converter

that transforms light intensity into a digital signal output

General Description

capable of direct I²C interface. The device 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.
