BH1750 Ambient Light Sensor Module

BH1750FVI Digital Ambient Light Intensity Sensor

The BH1750 is an optical sensor IC featuring an integrated 16-bit ADC that outputs calibrated light levels directly in standard Lux (lx) units. Eliminating calculations and calibrations, it rejects 50Hz/60Hz artificial light flicker and mimics the human eye spectral sensitivity.

Specifications

• Illuminance Range: 1 to 65,535 Lux (expandable to 100k Lux)
• High Resolution: 1 lx measurement mode
• Interface: I2C standard (supports 0x23 and 0x5C addresses)
• Operating Voltage: 3.3V to 5.0V (onboard regulator and I2C pull-ups)
• Low light dependency: Works reliably from moonlight to direct sunlight
• Spectral Response: Approximates human eye photopic curve
