This module is a digital ambient light sensor, IIC I2C communication. Good for arduino light detection 

  • Wide range and High resolution. ( 1 – 65535 lx )
  • Power Supply 3V-5V
  • 16bit AD converter built-in
  • Low Current by power down function * 50Hz / 60Hz Light noise reject-function
  • Light source dependency is little. ( ex. Incandescent Lamp. Fluorescent Lamp. Halogen Lamp. White LED. Sun Light )
  • Small measurement variation ( /- 20%)


  • Digital Light intensity detection module: GY-30 Chip : BH1750FVI
  • Power supply: 3V-5V power
  • Light range 0-65535 lx
  • Sensor built-in : 16 bitAD converter
  • Direct digital output, bypassing the complex calculation, bypassing the calibration
  • Don’t distinguish between ambient light
  • Close to the spectral characteristics of visual acuity
  • widely use to 1-lux high precision measurement
  • Standard NXP I2C communication agreement
