TSL25911FN Ambient Light Sensor 0 to 88000Lux Detection Range for Raspberry Pi, Arduino, STM32, Mobile Phone, etc.

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).

Key Features

• ✅ 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)
