Ambient light sensor manual#

TSL2591 use I2C interface, has a data line and a clock signal line.

The digital output can be inputted to a microprocessor where an empirical formula is used to derive illuminance in lux (ambient light level) to approximate the human eye response. Two integral ADCs convert the photodiode current into a digital output representing the irradiance measured on each channel. The sensor combines a wideband photodiode (visible and infrared) and an infrared response photodiode on a single CMOS integrated circuit that provides a near-light adaptive response over an effective 16-bit dynamic range (16-bit resolution). This product uses TSL25911FN, which is a light-intensity digitizer based on IIC bus communication. Communication interface: I2C (constant address: 0 x 29).

Ambient light sensor manual#

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

Adopts TSL25911FN, measures infrared plus visible light (wider range than TSL2561).

The output data uses a formula to derive the illuminance in lux (ambient light intensity) to approximate the human eye response. It can sense the ambient light intensity around and output it through the I2C interface. This module is an ambient light sensor with TSL25911 as its core.
