Overview

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.

Features

• 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)

Specifications

• Light sensor: TSL25911FN
• Communication interface: I2C (constant address: 0x29)
