Feature

●TSL25911FN is a very-high sensitivity light-to-digital converter that transforms light intensity into a digital signal output 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.
●High sensitivity up to 188uLux, wide dynamic range up to 600M:1. Embedded infrared-responding photodiode, allows precise measuring even on strong infrared noise environment.
●Embedded ADC, direct light intensity signal output to I2C interface, less noise jamming. Provides interrupt output with programmable upper and lower thresholds.
●CQRobot Ambient Light Sensor Built-in TSL25911FN chip, Onboard voltage translator, compatible with 3.3V/5V operating voltage, Compatible with Raspberry Pi, Arduino, STM32 and other motherboards. Adopts TSL25911FN, measures infrared plus visible light. (wider range than TSL2561)


Description

TSL25911FN 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. TSL25911FN supports traditional level-style interrupts and remains valid until the firmware is cleared.
CQRTSL25911 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, 3.3V/5V operating voltage, for Raspberry Pi/Arduino/STM32.
