Fermion: Light Sensor Breakout, BH1750 - 

SEN0097 is a Fermion: BH1750 light sensor (breakout). This is a BH1750 light intensity sensor breakout board with a 16bit AD converter built-in which can directly output a digital signal, there is no need for complicated calculations. This is a more accurate and easier to use version of the simple foto resistor which only outputs a voltage that needs to be calculated in order to obtain meaningful data. With the BH1750 light sensor intensity can be directly measured by the luxmeter, without needing to make calculations. The data which is output by this sensor is directly output in Lux (Lx). When objects which are lighted in homogeneous get the 1 lx luminous flux in one square meter, their light intensity is 1lx. Sometimes to take good advantage of the illuminant, you can add a reflector to the illuminant.
