Overview

The BH1750FVI-TR is a digital 16-bit ambient light sensor IC with an I2C interface that provides direct lux measurements without the need for complex calculations. It features a spectral response that closely matches the human eye and includes built-in noise rejection for 50Hz and 60Hz flickering light sources.

Why Choose This Part

This sensor offers a wide measurement range from 1 to 65535 lx with minimal infrared influence and high accuracy. It requires no external components for operation and supports 1.8V logic interfaces, making it easy to integrate into low-power embedded designs.

Applications

Display Brightness Control
Adjusting LCD and keypad backlighting in smartphones, tablets, and handheld devices based on ambient light levels.
Smart Lighting Systems
Controlling indoor or street lighting to maintain consistent illumination while minimizing power consumption.
Digital Camera Exposure
Providing precise ambient light data for determining shutter speeds and aperture settings in digital photography.

Getting Started

Engineers can begin development using standard I2C drivers on platforms like Arduino or Raspberry Pi, as the device provides a simple direct-read lux value. Ensure the VDD supply is maintained between 2.4V and 3.6V and utilize the ADDR pin to select between two possible I2C addresses for multi-sensor configurations.

Also Consider

TSL2591 ams OSRAM - Offers a much higher dynamic range and separate IR/visible light photodiodes for more complex light sensing environments.
OPT3001 TITexas Instruments - Provides a spectral response that is extremely close to the human eye with a smaller 2.0mm x 2.0mm footprint.
