ROHM BH1750FVI

This is an Arduino library for ROHM BH1750FVI Ambient Light Sensor

  • Default range: 1 - 65'535 lux
  • Measurement accuracy: ±20%, possible to calibrate
  • Peak wave length: 560nm, yellow-green
  • Power supply voltage: 2.4 - 3.6v

Supports all sensors features:

  • *Changing Sensitivity
  • Changing Resolution
  • Read Illuminance
  • Power Down
  • Power Up
  • Reset
  • Calibration

Tested on:

  • Arduino AVR
  • Arduino ESP8266
  • Arduino STM32

*This option is used to compensate the influence of the optical filter. For example, when transmission rate of optical window is 50% (measurement result becomes 0.5 times lower), influence of optical window is ignored by changing sensor sensitivity from default 1.0 to 2.0 times
