GY-30 BH1750 Intensity Digital Light Sensor Module

This is a BH1750FVI ( GY30 GY 30 GY - 30 / BH 1750 ) light intensity sensor module with built-in a 16 bit AD converter generating digital signal. The data from this module is light intensity in lx (lux meter). It communicates with the micro-controller board through I2C bus. Specifications: Working Voltage: 3.3V~6V I2C bus Interface with 2 alternative address (f/s Mode Support) Spectral responsibility is approximately human eye response Wide range and High resolution (1 ~ 65535 lx) Light source dependency is little. (ex. Incandescent Lamp, Fluorescent Lamp, Halogen Lamp, White LED, Sun Light) Adjustable measurement result for influence of optical window (It is possible to detect min. 0.11 lx, max. 100000 lx by using this function.) (1 ~ 65535 lx) The influence of infrared is very small. Small measurement variation (+/- 20%)
