BH1750 Light Intensity measurement Module

BH1750 I2C Light Sensor Module

This module interfaces to the BH1750 Light Sensor made by Rohm Semiconductor. This is a simple, inexpensive light sensor which provides reasonably accurate, quantitative values for the light level. The BH1750 can be operated in continuous or single measurement mode, and has resolution settings of 0.5 lx, 1 lx, and 4 lx, and communicates over I2C. This offers a way to measure light levels more accurately and consistently than using a light-dependent resistor.
