Note: if bOverLimit=1 and the default ALS configuration is used, the measurement of fLux should not be considered and the actual max value depends on the type of light. Ranges from 12.5K - 17.5K. | |||

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). | |||
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. | |||
