TSL25911 High Sensitivity Digital Ambient Light Sensor, Wide Dynamic Range, I2C Interface


This is a high sensitivity digital ambient light sensor module based on TSL25911, features 600M:1 wide dynamic range, detects light intensity up to 88000Lux, controlled via I2C interface, low power consumption. It is capable of operating across various light environment.


  • 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 on strong infrared noise environment
  • 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)


  • Light sensor: TSL25911FN
  • Communication interface: I2C (constant address: 0x29)
  • Effective range: 0~88000Lux
  • Operating voltage: 3.3V/5V
