- | + | Note: please check! This might only be one of the two different spectral channels and thus yield vastly incorrect LUX values when massive IR or UV light has impact on the sensor. The lux value of N900 is generic and derived from an algorithm calculating ''visible'' lux from roughly a difference between the two sensor values the ALS provides | |
