−
The BH1730 outputs 2 values. Visible light and IR light. This is then calculated through an algorithm that checks for Gain, Measurement time, filter qualities and ouputs lux (max correct measurement of 100K lux).
+
No input. Outputs lux in float.
−
The default values are Gain 64x and ITIME of 38 (256 - 218). This allows for a max lux value of 17972 lux when visible light value is maximum and IR light is 0. When both of them are on their limit, the output is 1192 lux.

The sensor is fully configurable.
